Korean Air Lines Flight 007


Korean AirLines Flight 007 KAL 007, KE 007 was a Korean Air Lines civilian airliner that was shot down by Soviet interceptors on 1 September 1983, over the Sea of Japan (East Sea), near Moneron Island just west of Sakhalin island. All 269 passengers and crew aboard were killed, including Lawrence McDonald, a sitting member of the United States Congress. The aircraft was en route from New York City to Seoul via Anchorage when it strayed into prohibited Soviet airspace around the time of a planned missile test.

The Soviet Union initially denied knowledge of the incident, but later admitted shooting the aircraft down, claimingat it was on a spy mission. The Politburo said it was a deliberate provocation by the United States, to test the Soviet Union's military preparedness, or even to provoke a war. The United States accused the Soviet Union of obstructing search and rescue operations. The Soviet military suppressed evidence sought by the International Civil Aviation Organization (ICAO) investigation, notably the flight data recorders, which were eventually released eight years later after the collapse of the Soviet Union.

The incident was one of the tensest moments of the Cold War, and resulted in an escalation of anti-Soviet sentiment, particularly in the United States. The opposing points of view on the incident were never fully resolved; consequently, several groups continue to dispute official reports and offer alternate theories of the event. The subsequent release of transcripts and flight recorders by the Russian Federation has addressed some details.
As a result of the incident, the United States altered tracking procedures for aircraft departing Alaska, while the interface of the autopilot used on airliners was redesigned to make it more ergonomic. President Ronald Reagan ordered the U.S. military to make the developing Global Positioning System (GPS) available for civilian use so that navigational errors like that of KAL 007 could be averted in the future.


Korean Air Lines Flight 007 was a commercial Boeing 747-230B delivered on January 28, 1972, with the serial number CN20559/186 and registration HL7442 (formerly D-ABYH operated by Condor Flugdienst). The aircraft departed Gate 15 of John F. Kennedy International Airport, New York City on 30 August 1983 bound for Seoul, 35 minutes behind its scheduled departure time of 23:50 EDT (0350 UTC, 31 August). The flight was carrying 246 passengers and 23 crew members. After refueling at Anchorage International Airport in Anchorage, Alaska, the aircraft, piloted on this leg of the journey by Captain Chun Byung-in, departed for Seoul at 1300 UTC (4:00 AM Alaska Time) on 31 August 1983.
The aircrew had an unusually high ratio of crew to passengers, as six deadheading crew were onboard.Twelve passengers occupied the upper deck first class, while in business almost all of 24 seats were taken; in economy class, approximately 80 seats did not contain passengers. There were 22 children under the age of 12 years aboard. U.S. congressman Lawrence McDonald from Georgia, who at the time was also the second president of the conservative John Birch Society, was on the flight. One hundred thirty passengers planned to connect to other destinations such as Tokyo, Hong Kong, and Taiwan. Senator Jesse Helms of North Carolina, Senator Steven Symms of Idaho, and Representative Carroll J. Hubbard, Jr. of Kentucky were aboard sister flight KAL 015, which flew 15 minutes behind KAL 007; they were headed to Seoul, Korea in order to attend the ceremonies for the 30 year anniversary of the U.S.-Korea Mutual Defense Treaty.

Flight deviation from assigned route
After taking off from Anchorage, the flight was instructed by Air Traffic Control (ATC) to turn to a heading of 220 degrees. Approximately 90 seconds later, ATC directed the flight to "proceed direct Bethel when able". Upon arriving over Bethel, flight 007 would enter the northernmost of five 50-mile (80 km) wide airways, known as the NOPAC (North Pacific) routes, that bridge the Alaskan and Japanese coasts. KAL 007's particular airway, R-20 (Romeo 20), passes just 17.5 miles (28.2 km) from Soviet airspace off the Kamchatka coast.
The autopilot system used at the time had four basic control modes: HEADING, VOR/LOC, ILS and INS. The HEADING mode maintained a constant magnetic course, selected by the pilot. The VOR/LOC mode maintained the plane on a specific course, transmitted from a ground VOR or Localizer beacon, selected by the pilot. The ILS mode caused the plane to track both vertical and lateral course beacons, which led to a specific runway, selected by the pilot. The INS mode maintained the plane on lateral course lines between selected flight plan waypoints, programmed into the INS computer navigation system.
When the INS navigation systems were properly programmed with the filed flight plan waypoints, the pilot could turn the autopilot mode selector switch to the INS position and the plane would then automatically track the programmed INS course line, provided the plane was headed in the proper direction and within 7.5 nautical miles (13.9 km) of the INS course line. The HEADING mode of the autopilot would normally be engaged sometime after takeoff to comply with vectors from ATC, and then after receiving appropriate ATC clearance, to guide the plane to intercept the desired INS course line.


The Anchorage VOR beacon was not operational because of maintenance. The crew received a NOTAM (Notice to Airmen) of this fact, which was not seen as a problem, as the captain could still check his position at the next VORTAC beacon at Bethel, 346 miles (557 km) away. The aircraft was required to maintain the assigned heading of 220 degrees, until it could receive the signals from Bethel, then it could fly direct to Bethel, as instructed by ATC, by centering the VOR "to" course deviation indicator (CDI) and then engaging the auto pilot in the VOR/LOC mode. Then, when over the Bethel beacon, the flight could start using INS mode to follow the waypoints comprising route Romeo-20 around the coast of the U.S.S.R. to Seoul. The INS mode was necessary for this route, since after Bethel the plane would be mostly out of range from VOR stations.

 (dotted line) and actual flight paths
At about 10 minutes after take-off, KAL 007, flying on a heading of 245 degrees, began to deviate to the right (north) of its assigned route to Bethel; it would continue to fly on this constant heading for the next five and a half hours.
International Civil Aviation Organization (ICAO) simulation and analysis of the flight data recorder determined that this deviation was probably caused by the aircraft's auto pilot system operating in HEADING mode, after the point that it should have been switched to the INS mode. According to the ICAO, the autopilot was not operating in the INS mode for one of two reasons. Either the crew did not switch the autopilot to the INS mode (shortly after Cairn Mountain) or they did select the INS mode, but it did not activate because the aircraft had already deviated off track by more than the 7.5 nautical miles (13.9 km) tolerance permitted by the inertial navigation computer. In both scenarios, the autopilot remained in the HEADING mode, and the problem was not detected by the crew.
At 28 minutes after take-off, civilian radar at Kenai, on the eastern shore of Cook Inlet and with radar coverage 175 miles (282 km) west of Anchorage, tracked KAL 007 5.6 miles (9.0 km) north of where it should have been.
When KAL 007 did not reach Bethel at 50 minutes after takeoff, military radar at King Salmon, Alaska, tracked KAL 007 at 12.6 nautical miles (23.3 km) north of where it should have been. There is no evidence to indicate that civil air traffic controllers or military radar personnel at Elmendorf Air Force Base (who were in a position to receive the King Salmon radar output) were aware of KAL 007's deviation in real-time, and therefore able to warn the aircraft. It had exceeded its expected maximum deviation sixfold, 2 nautical miles (3.7 km) of error being the maximum expected drift from course if the inertial navigation system was activated.
KAL 007's divergence prevented the aircraft from transmitting its position via shorter range very high frequency radio (VHF). It therefore requested KAL 015, also en route to Seoul, to relay reports to air traffic control on its behalf. KAL 007 requested KAL 015 to relay its position three times in total. At 1443 UTC, KAL 007 directly transmitted a change of estimated time of arrival for its next waypoint, NEEVA, to the international flight service station at Anchorage, but it did so over the longer range high frequency radio (HF) rather than VHF. HF transmissions are able to carry a longer distance than VHF, but are vulnerable to interference and static; VHF are clearer with less interference, and preferred by flight crews. The inability to establish direct radio communications to be able to transmit their position directly did not alert the pilots of KAL 007 of their ever increasing divergence and was not considered unusual by air traffic controllers. Halfway between Bethel and waypoint NABIE, KAL 007 passed through the southern portion of the North American Air Defense buffer zone. This zone, monitored intensively by the American National Security Agency, is north of Romeo 20 and deemed off-limits to civilian aircraft.
Some time after leaving American territorial waters, KAL Flight 007 crossed the International Date Line, where local date shifted from 31 August 1983 to 1 September 1983.
KAL 007 continued its journey, ever increasing its deviation—60 nautical miles (110 km) off course at waypoint NABIE, 100 nautical miles (190 km) off course at waypoint NUKKS, and 160 nautical miles (300 km) off course at waypoint NEEVA—until it reached the Kamchatka Peninsula.

Flight crew awareness of deviation
The reasons put forward for the aircraft's deviation range from a lack of situational awareness by the pilots (ICAO), to a planned and intentional deviation (Pearson), to an Inertial Navigation system (INS) programming error by 10 degrees of longitude during the inputing of the ramp starting position by the crew (Hersh pp. 199–213, the "Harold Ewing (H/E) scenario," which ICAO studied in great detail). All accounts note that the pilots had several sources of information that could have alerted them to their increasing deviation from their planned route. The H/E scenario additionally suggests the flight's first officer did know they were flying away from the planned course, but the airline's culture discouraged anyone from questioning the captain's conduct of the flight, so he remained silent.
The horizontal situation indicator (HSI): Pearson contends that the HSI’s needle could have alerted the pilots of their course deviation. He postulates that the needle of each pilot's HSI, capable of showing deviation only up to 8 nautical miles (15 km), should have been “pegged” all the way to the side. The pilots, thus, could in theory have known that they were at least 8 nautical miles (15 km) off course.
Despite this, at 1349 UTC, the pilots were reporting that they were on course ("007, Bethel at forty niner.") Fifty minutes after takeoff, military radar at King Salmon, Alaska acquired KAL 007 at more than 12.6 nautical miles (23.3 km) off course. The deviation exceeded the expected accuracy of the INS (2 nautical miles (3.7 km) an hour) by a factor of six.
Difficulties in making required reports: Pilot and copilot could also have been aware of the aircraft’s serious deviation because now, much more than 12 nautical miles (22 km) off course, KAL 007 was too far off course for the pilots to make their required Very High Frequency (VHF) radio reports, and had to relay these reports via KAL Flight 015, just minutes behind and on course (KAL 007, increasingly off course, relied on KAL 015 three times to relay its reports to Anchorage Air Traffic Control). By being forced to rely on KAL 015 to relay messages, KAL 007 should have (by definition) understood that they were well off course.
At one point in this section of its flight, (1443 UTC) KAL 007 put a call through a navigational "hookup", the International Flight Service Station on HF. Flight 007, now too distant to speak directly with Anchorage controller through VHF, was transmitting its message using HF. At another point of this section of the flight, at waypoint NABIE, KAL 007 was too far north to make radio contact with the VHF air traffic control relay station on St. Paul Island. KAL 015 relayed for KAL 007. The message was a change in the estimated time of arrival (ETA) for the next waypoint called NEEVA, delaying by four minutes the ETA that KAL 015 had previously relayed on behalf of KAL 007. Since a revised ETA could only be calculated by means of readout information presented by KAL 007’s Inertial Navigation Systems Control Display unit, Pearson asserts that pilot and copilot were once again presented with the opportunity of verifying their position and becoming aware of their enormous deviation.
Contrary wind conditions of KAL 007 and KAL 015: KAL 015 had departed about 15 minutes behind KAL 007. About 23 minutes before the tragedy, the two aircraft compared the times that they expected to reach waypoint NOKKA, at which point it became apparent that KAL 015 would reach it only four minutes behind KAL 007. KAL 015 reported experiencing strong tailwinds, while KAL 007 was experiencing a headwind. The paradox of the different flying conditions experienced by two aircraft supposedly flying so close together was discussed in the cabin of KAL 007, but the crew failed to draw any conclusions from it.
Weather radar: There was one last aid to warn the crew. With consoles at the knees of both pilot and copilot, the plane’s weather radar [Notes 4] could have alerted them, both over Kamchatka and later over Sakhalin, to the fact that they were no longer flying over water, as they should have been. Weather radar has two modes—ground mapping (when it would be possible to look down and see water or land masses as well as the contours of the coast lines) and weather surveillance mode for thunderstorm detection. In ground mapping mode, KAL 007 had only to make sure that the land mass of Kamchatka and the island string of the Kurile chain would remain to the right. That night, KAL 007’s weather radar was probably not in land mapping mode, for the weather was inclement.The ICAO's meteorological analysis concluded that "there was extensive coverage of low, medium, and high level clouds over southern Kamchatka associated with an active cold front".” ICAO’s analysis of KAL 007’s weather radar functioning would state, "it was concluded that the radar was not functioning properly or that the ground mapping capability was not used".”
According to the ICAO, an indicator of pilot unawareness of the deviation from route of their flight was the bantering and casual cockpit conversation at the times that awareness of deviation into hostile airspace would have increased tension and have precluded this.

IIn 1983, Cold War tensions had escalated because of several factors. These included the United States's Strategic Defense Initiative, its planned deployment of Pershing II missiles in Europe in March and April, and FleetEx '83, the largest fleet exercise held to date in the North Pacific. Aircraft from USS Midway and USS Enterprise repeatedly overflew Soviet military installations in the Kurile Islands during FleetEx '83,resulting in the dismissal or reprimanding of Soviet military officials who had been unable to shoot them down. On the Soviet side, Operation RYAN was expanded. Lastly, there was a heightened alert around the Kamchatka Peninsula at the time KAL 007 was in the vicinity, because of a Soviet missile test that was scheduled for the same day. A United States Air Force RC-135 reconnaissance aircraft (another Boeing aircraft based on the civilian Boeing 707 four-engined airliner) flying in the area was monitoring the missile test off the peninsula.

At 1551 UTC, according to Soviet sources, KAL 007 entered the restricted airspace of Kamchatka Peninsula. The buffer zone extended 200 kilometres (120 mi) from Kamchatka's coast and is known as a Flight Information Region (FIR). The 100-kilometre (62 mi) radius of the buffer zone nearest to Soviet territory had the additional designation of prohibited airspace. When KAL 007 was about 80 miles (130 km) from the Kamchatka coast, one MiG-23 and three Su-15 Flagon fighters were scrambled to intercept the Boeing 747. Significant command and control problems were experienced trying to vector the fast military jets onto the Boeing before they ran out of fuel. In addition, pursuit was made more difficult, according to Soviet Air Force Captain Alexander Zuyev, who defected to the West in 1989, because Arctic gales had knocked out Soviet radar ten days before. The unidentified jetliner therefore crossed over the Kamchatka Peninsula back into international airspace over the Sea of Okhotsk without being intercepted.
The Commander of the Soviet Far East District Air Defense Forces, General Valeri Kamensky, was adamant that KAL 007 was to be destroyed even over neutral waters but only after positive identification showed it not to be a passenger plane. His subordinate, General Anatoly Kornukov, commander of Sokol Air base (later to become commander of the Russian Air Force), was adamant that there was no need to make positive identification as "the intruder" had already flown over Kamchatka.
General Kornukov (to Military District Headquarters-Gen. Kamenski): (5:47) "...simply destroy [it] even if it is over neutral waters? Are the orders to destroy it over neutral waters? Oh, well." Kamenski: We must find out, maybe it is some civilian craft or God knows who." Kornukov: "What civilian? [It] has flown over Kamchatka! It [came] from the ocean without identification. I am giving the order to attack if it crosses the State border."
Soviet Sukhoi Su-15 Flagon interceptor
Soviet Air Defence Force units that had been tracking the Korean aircraft for more than an hour while it entered and left Soviet airspace now classified the aircraft as a military target when it re-entered their airspace over Sakhalin Island. After the protracted ground-controlled interception, the three Su-15 fighters (from nearby Dolinsk-Sokol airbase) and the MiG-23 (from Smirnykh Air Base) managed to make visual contact with the Boeing. The pilot of the lead Su-15 fighter fired warning shots, but recalled later in 1991:
“ I fired four bursts, more than 200 rounds. For all the good it did. After all, I was loaded with armor piercing shells, not incendiary shells. It's doubtful whether anyone could see them... ”
At this point, KAL 007 contacted Tokyo air traffic control requesting clearance to ascend to a higher flight level for reasons of fuel economy; the request was granted, so the Boeing started to climb, gradually slowing as it exchanged speed for altitude. The decrease in speed caused the pursuing fighter to overshoot the Boeing, an action that was interpreted by the Soviet pilot as an evasive maneuver. The order to shoot KAL 007 down was given as it was about to leave Soviet airspace for the second time. At around 1826 UTC, under pressure from General Anatoly Kornukov, Commander of Sokol Air Bases on Sakhalin, and ground controllers not to let the aircraft escape into international airspace, the lead fighter was able to move back into a position where it could fire two Kaliningrad K-8 air-to-air missiles at the plane.


Soviet pilot's recollection of shootdown
In a 1991 interview with Izvestia, Major Genadi Osipovich, pilot of the Su-15 interceptor that shot the 747 down, spoke about his recollections of the events leading up to the shootdown. Contrary to official Soviet statements at the time, he recalled telling ground controllers that there were blinking lights...." He continued, saying that "I saw two rows of windows and knew that this was a Boeing. I knew this was a civilian plane. But for me this meant nothing. It is easy to turn a civilian type of plane into one for military use..." He furthermore did not provide a detailed description of the aircraft to his ground controllers: "I did not tell the ground that it was a Boeing-type plane; they did not ask me."
Commenting on the moment that KAL 007 slowed as it ascended from flight level 330 to flight level 350, and then on his maneuvering for missile launch, Osipovich said:
"They [KAL 007] quickly lowered their speed. They were flying at 400 kilometers per hour. My speed was more than 400. I was simply unable to fly slower. In my opinion, the intruder's intentions were plain. If I did not want to go into a stall, I would be forced to overshoot them. That's exactly what happened. We had already flown over the island [Sakhalin]. It is narrow at that point, the target was about to get away… Then the ground [controller] gave the command: 'Destroy the target…!' That was easy to say. But how? With shells? I had already expended 243 rounds. Ram it? I had always thought of that as poor taste. Ramming is the last resort. Just in case, I had already completed my turn and was coming down on top of him. Then, I had an idea. I dropped below him about 2,000 meters… afterburners. Switched on the missiles and brought the nose up sharply. Success! I have a lock on."
"We shot down the plane legally... Later we began to lie about small details: the plane was supposedly flying without running lights or strobe light, that tracer bullets were fired, or that I had radio contact with them on the emergency frequency of 121.5 megahertz."

Soviet command hierarchy of shootdown

The Soviet real-time military communication transcripts of the shootdown suggest the chain of command from the top general to Major Osipovich, the SU-15 interceptor pilot who shot down KAL 007. In reverse order, they are:
Major Gennady Osipovich,
Lt. Colonel Titovnin, Combat Control Center - Fighter Division
Lt. Colonel Maistrenko, Smirnykh Air Base Fighter Division Acting Chief of Staff, who confirmed the shootdown order to Titovnin
"Titovnin: You confirm the task?
"Maistrenko: Yes."
Lt. Colonel Gerasimenko, Acting Commander, 41st Fighter Regiment.
"Gerasimenko: (to Kornukov) Task received. Destroy target 60-65 with missile fire. Accept control of fighter from Smirnikh."
General Anatoly Kornukov, Commander of Sokol Air Base - Sakhalin.
"Kornukov: (to Gerasimenko) I repeat the task, Fire the missiles, Fire on target 60-65. Destroy target 60-65...Take control of the MiG 23 from Smirnikh, call sign 163, call sign 163 He is behind the target at the moment. Destroy the target!...Carry out the task, Destroy it!"
General Valery Kamensky, Commander of Far East Military District Air Defence Forces.
"Kornukov: (To Kamenski) ...simply destroy [it] even if it is over neutral waters? Are the orders to destroy it over neutral waters? Oh, well."
General Ivan Moiseevich Tretyak, Commander of the Far East Military District.
"Weapons were used, weapons authorized at the highest level. Ivan Moiseevich authorized it. Hello, hello.", "Say again.", "I cannot hear you clearly now.", "He gave the order. Hello, hello, hello.", "Yes, yes.", "Ivan Moiseevich gave the order, Tretyak.", "Roger, roger.", "Weapons were used at his order."

Post-attack flight
ICAO chart of KAL 007's flight for the 144 seconds after missile attack.

At the time of the attack, the plane had been cruising at an altitude of about 35,000 feet (11,000 m). Tapes recovered from the airliner's cockpit voice recorder indicate that the crew were unaware that they were off course and violating Soviet airspace. Immediately after missile detonation, the airliner began a 113-second arc upward because of a damaged cross-over cable between the left inboard and right outboard elevators. At 1826:46 UTC, at the apex of the arc at altitude 38,250 feet (11,660 m), either the pilot was able to turn off the autopilot or the autopilot tripped and the plane began to descend to 35,000 feet (11,000 m). From 1827:01 until 1827:09, the flight crew reports to Tokyo Radio informing that KAL 007 to "descend to 10,000" [feet]. At 1827:20, ICAO graphing of Digital Flight Data Recorder tapes show that after a descent phase and a 10 second "nose-up", KAL 007 is now leveled out at pre-missile detonation altitude of 35,000 ft (11,000 m), forward acceleration is now back to pre-missile detonation rate of zero acceleration, and air speed has returned to pre-detonation velocity. Yaw (oscillations), begun at the time of missile detonation, continue decreasingly until the end of the minute 44 second portion of the tape. The Boeing did not break up, explode or plummet immediately after the attack; it continued its gradual descent for four minutes, then leveled off at 16,424 feet (1830–1831 UTC), rather than continue descending to 10,000 as previously reported to Tokyo Radio, continuing at this altitude for almost five more minutes (1835 UTC). The last cockpit voice recorder entry occurred at 1827:46 while in this phase of the descent. At 1828 UTC, the aircraft was reported turning to the north.ICAO analysis concluded that the flight crew "retained limited control" of the aircraft. Finally, the aircraft began to descend in spirals over Moneron Island before coming down 2.6 miles (4.2 km) , killing all 269 on board. The aircraft was last seen visually by Osipovich, "somehow descending slowly" over Moneron Island. The aircraft disappeared off long range military radar at Wakkanai, Japan at a height of 1,000 feet (300 m).
KAL 007 was probably attacked in international airspace, with a 1993 Russian report listing the location of the missile firing outside its territory at 46°46′27″N 141°32′48″E, although the intercepting pilot stated otherwise in a subsequent interview. Initial reports that the airliner had been forced to land on Sakhalin were soon proved false. One of these reports conveyed via phone by Orville Brockman, the Washington office spokesman of the Federal Aviation Administration to the press secretary of Larry McDonald was that the FAA in Tokyo had been informed by the Japanese Civil Aviation Bureau that "Japanese self-defense radar force confirms that the Hokkaido radar followed Air Korea to a landing in Soviet territory on the island of Sakhalinska and it is confirmed by the manifest that Congressman McDonald is on board".
A Japanese fisherman aboard the 58th Chidori Maru later reported to the Japanese Maritime Safety Agency of hearing a plane at low altitude but did not see it. Then he heard "a loud sound followed by a bright flash of light on the horizon, then another dull sound and a less intense flash of light on the horizon" as well as smelling aviation fuel.

Soviet command response to post-detonation flight
Though the interceptor pilot reported to ground control, "Target destroyed", the Soviet command, from General on down, indicated surprise and consternation at KAL 007's continued flight, and ability to regain its altitude and maneuver. This consternation continued through to KAL 007's subsequent level flight at altitude 16,424 ft (5,006 m). and then through its spiral descent over Moneron Island. (See transcript from 18:26 onwards: "Lt. Col. Novoseletski: Well, what is happening, what is the matter, who guided him in, he locked on, why didn’t he shoot it down?")

Missile damage to plane
The following damage to the aircraft was determined by the ICAO from its analysis of the flight data recorder and cockpit voice recorder:
The Hydraulics: KAL 007 had four redundant hydraulic systems of which systems one, two, and three were damaged or destroyed. There was no evidence of damage to system four. The hydraulics provided actuation for all the primary flight controls; all secondary flight controls (except leading edge Krueger flaps); and landing gear retraction, extension, gear steering, and wheel braking. Each primary flight control axis received power from all four hydraulic systems. Upon missile detonation, the jumbo jet began to experience oscillations (yawing) as the dual channel yaw damper was damaged. Yawing would not have occurred if hydraulic systems one or two were fully operational. The result is that the control column does not thrust forward upon impact (it should have done so as the plane was on autopilot) to bring down the plane to its former altitude of 35,000 feet (11,000 m). This failure of the autopilot to correct the rise in altitude indicates that hydraulic system number three, which operates the autopilot actuator, a system controlling the plane's elevators, was damaged or out. KAL 007's airspeed and acceleration rate both began to decrease as the plane began to climb. At twenty seconds after missile detonation a click was heard in the cabin, which is identified as the "automatic pilot disconnect warning" sound. Either the pilot or co-pilot had disconnected the autopilot and was manually thrusting the control column forward in order to bring the plane lower. Though the autopilot had been turned off, manual mode did not begin functioning for another twenty seconds. This failure of the manual system to engage upon command indicates failure in hydraulic systems one and two. With wing flaps up, "control was reduced to the right inboard aileron and the innermost of spoiler section of each side".
Left Wing: Contrary to Major Osipovich's statement in 1991 that he had taken off half of KAL 007's left wing, ICAO analysis found that the wing was intact: "The interceptor pilot stated that the first missile hit near the tail, while the second missile took off half the left wing of the aircraft... The interceptor's pilot's statement that the second missile took off half of the left wing was probably incorrect. The missiles were fired with a two-second interval and would have detonated at an equal interval. The first detonated at 1826:02 UTC. The last radio transmissions from KE007 to Tokyo Radio were between 1826:57 and 1827:15 UTC using HF [high frequency]. The HF 1 radio aerial of the aircraft was positioned in the left wing tip suggesting that the left wing tip was intact at this time. Also, the aircraft's maneuvers after the attack did not indicate extensive damage to the left wing."
Engines: The co-pilot reported to Captain Chun twice during the flight after the missile's detonation, "Engines normal, sir."
Tail Section: The first missile was radar-controlled and proximity fuzed, and detonated 50 metres (160 ft) behind the aircraft. Sending fragments forward, it either severed or unraveled the crossover cable from the left inboard elevator to the right elevator. This, with damage to one of the four hydraulic systems, caused KAL 007 to ascend from 35,000 feet (11,000 m) to 38,250 feet (11,660 m), at which point the autopilot was disengaged.
Fuselage: Tiny shrapnel from the proximity-fuzed air-to-air missile that detonated 50 metres (160 ft) behind the aircraft, punctured the fuselage and caused rapid decompression of the pressurised cabin. The interval of 11 seconds between the sound of missile detonation picked up by the cockpit voice recorder and the sound of the alarm sounding in the cockpit enabled ICAO analysts to determine that the total size of the tiny ruptures to the pressurized fuselage was 1.75 square feet (0.163 m2)

Search and rescue

As a result of Cold War tensions, the search and rescue operations of the Soviet Union were not co-ordinated with those of the United States, South Korea, and Japan. Consequently no information was shared, and each side endeavoured to harass or obtain evidence to implicate the other.The flight data recorders were the key pieces of evidence sought by both factions, with the United States insisting that an independent observer from the ICAO be present on one of its search vessels in the event that they were found. International boundaries are not well defined on the open sea, leading to numerous confrontations between the large number of opposing naval ships that were assembled in the area.

The Soviets did not acknowledge shooting down the aircraft until 6 September. Eight days after the shootdown, Marshal of the Soviet Union and Chief of General Staff Nikolai Ogarkov denied knowledge of where KAL 007 had gone down, "We could not give the precise answer about the spot where it [KAL 007] fell because we ourselves did not know the spot in the first place." But nine years after, the Russian Federation handed over transcripts of Soviet military communications that showed that at least two documented search and rescue (SAR) missions were ordered within a half hour of the attack to the last Soviet verified location of the descending jumbo jet, over Moneron Island: The first search was ordered from Smirnykh Air Base in central Sakhalin at 18:47 GMT, 9 minutes after KAL 007 had disappeared from Soviet radar screens, and brought rescue helicopters from Khomutovo Air base, the civilian and military airport at Yuzhno-Sakhalinsk City in southern Sakhalin, and KGB boats to the area. The second search was ordered 8 minutes later by the Deputy Commander of the Far Eastern Military District, Gen. Strogov, and involved civilian trawlers that were in the area around Moneron. "The border guards. What ships do we now have near Moneron Island, if they are civilians, send [them] there immediately." Moneron is just 4.5 miles (7.2 km) long and 3.5 miles (5.6 km) wide, located 24 miles (39 km) due west of Sakhalin Island at 46°15′N 141°14′E; it is the only land mass in the whole Tatar Straits.

Human remains and artifacts

Surface finds
Passengers' footwear retrieved by Soviets from the crash site,.
No body parts were recovered by the Russians from the surface of the sea in their territorial waters, though they would later turn over clothes and shoes to a joint U.S.–Japanese delegation to Nevelsk on Sakhalin. On Monday, 26 September 1983, a delegation of seven Japanese and American officials arriving aboard the Japanese patrol boat Tsugaru, had met a six-man Soviet delegation at the port of Nevelsk on Sakhalin Island. KGB Major General A. I. Romanenko, the Commander of the Sakhalin and Kuril Islands frontier guard, headed the Soviet delegation. Romanenko handed over to the Americans and Japanese, among other things, single and paired footwear. With footwear that the Japanese also retrieved, the total came to 213 men's, women's and children's dress shoes, sandals, and sports shoes. The Soviets said that all that they had retrieved, they had found floating in the water or washed up on the shores of Sakhalin and Moneron islands.
Family members of KAL 007 passengers later stated that these shoes were worn by their loved ones for the flight. Sonia Munder had no difficulty recognizing the sneakers of her children, one of Christian age 14 and one of Lisi age 17, by the intricate way her children laced them. Another mother says, "I recognized them just like that. You see, there are all kinds of inconspicuous marks which strangers do not notice. This is how I recognized them. My daughter loved to wear them." And yet another mother, Nan Oldham, identified her son John's sneakers from a photo in Life magazine of 55 of the 213 shoes—apparently, a random array on display those first days at Chitose Air Force Base in Japan. "We saw photos of his shoes in a magazine," says Oldham, "We followed up through KAL and a few weeks later, a package arrived. His shoes were inside: size 11 sneakers with cream white paint." John Oldham had taken his seat in row 31 of KAL 007 wearing those cream white paint-spattered sneakers.
Nothing was found by the joint U.S.–Japanese–South Korean search and rescue/salvage operations in international waters at the designated crash site or within the 225-square-nautical-mile (770 km2) search area.

Hokkaido finds
Eight days after the shootdown, human remains appeared on the north shore of Hokkaido, Japan. Hokkaido is about 30 miles (48 km) below the southern tip of Sakhalin across the Soya Strait (the southern tip of Sakhalin is 35 miles (56 km) from Moneron Island which lies to the west of Sakhalin). The ICAO concluded that these objects were carried from Russian waters to the shores of Hokkaido by the southerly current west of Sakhalin Island. All currents of the Tsushima Strait relevant to Moneron Island flow to the north, except this southerly current between Moneron Island and Sakhalin Island.
These human remains, including body parts, tissues, and two partial torsos, totaled 13. All were unidentifiable, but one partial torso was that of a Caucasian woman as indicated by auburn hair on a partial skull, and one partial body was of an Asian child (with glass imbedded). There was no luggage recovered. Of the non-human remains that the Japanese recovered were various items including dentures, newspapers, seats, books, eight KAL paper cups, shoes, sandals, and sneakers, a camera case, a "please fasten seat belt" sign, an oxygen mask, a handbag, a bottle of dish washing fluid, several blouses, an identity card belonging to 25-year-old passenger Mary Jane Hendrie of Sault Ste. Marie, Ontario, Canada, and the business card of passenger Kathy Brown-Spier.These items generally come from the passenger cabin of an aircraft. None of the items found generally come from the cargo hold of a plane, such as suitcases, packing boxes, industrial machinery, instruments, and sports equipment.

Soviet diver reports

Moneron Island
In 1991, Russian newspaper Izvestia published a series of interviews with Soviet military personnel who had been involved in salvage operations to find and recover parts of the aircraft. After three days of searching using trawlers, side-scan sonar, and diving bells, the aircraft wreckage was located by Russian searchers at a depth of 174 metres (571 ft) near Moneron Island. Since no human remains or luggage were found on the surface in the impact area, the divers expected to find the remains of passengers who had been trapped in the submerged wreckage of the aircraft on the seabed. When they visited the site two weeks after the shootdown, they found that the wreckage was in small pieces and no bodies:
"I had the idea that it would be intact. Well, perhaps a little banged up... The divers would go inside the aircraft and see everything there was to see. In fact it was completely demolished, scattered about like kindling. The largest things we saw were the braces which are especially strong—they were about one and a half or two meters long and 50–60 centimeters wide. As for the rest—broken into tiny pieces..."
According to Izvestia, the divers had only 10 encounters with passenger remains (tissues and body parts) in the debris area, including one partial torso.
Tinro ll submersible Captain Mikhail Igorevich Girs' diary: Submergence 10 October. Aircraft pieces, wing spars, pieces of aircraft skin, wiring, and clothing. But—no people. The impression is that all of this has been dragged here by a trawl rather than falling down from the sky…’
Viyacheslav Popov: "I will confess that we felt great relief when we found out that there were no bodies at the bottom. Not only no bodies; there were also no suitcases or large bags. I did not miss a single dive. I have quite a clear impression: The aircraft was filled with garbage, but there were really no people there. Why? Usually when an aircraft crashes, even a small one... As a rule there are suitcases and bags, or at least the handles of the suitcases."
A number of civilian divers, whose first dive was on 15 September, two weeks after the shootdown, state that Soviet military divers and trawls had been at work before them:
Diver Viyacheslav Popov: "As we learned then, before us the trawlers had done some ‘work’ in the designated quadrant. It is hard to understand what sense the military saw in the trawling operation. First drag everything haphazardly around the bottom by the trawls, and then send in the submersibles?...It is clear that things should have been done in the reverse order.”
ICAO also interviewed a number of these divers for its 1993 report: "In addition to the scraps of metal, they observed personal effects, such as clothing, documents and wallets. Although some evidence of human remains was noticed by the divers, they found no bodies."

Search for KAL 007 in international waters
From early in September until the beginning of November, the U.S. with the Japanese and South Koreans carried out joint search and rescue and then salvage operations. Rear Admiral Walter T. Piotti Jr, commander of Task Force 71 of 7th Fleet would summarize the U.S. and allied and then the Soviets’ Search and Salvage operations:
“Not since the search for the hydrogen bomb lost off Palomares, Spain has the U.S. Navy undertaken a search effort of the magnitude or import of the search for the wreckage of KAL Flight 007.”
“Within six days of the downing of KAL 007, the Soviets had deployed six ships to the general crash site area. Over the next 8 weeks of observation by U.S. naval units this number grew to a daily average of 19 Soviet naval, naval-associated and commercial (but undoubtedly naval subordinated) ships in the Search and Salvage (SAS) area. The number of Soviet ships in the SAS area over this period ranged from a minimum of six to a maximum of thirty-two and included at least forty-eight different ships comprising forty different ship classes.”

These missions met with interference by the Soviets, in violation of the 1972 Incident at Sea agreement, and included false flag and fake light signals, sending an armed boarding party to threaten to board a U.S.-chartered Japanese auxiliary vessel (blocked by U.S. warship interposition), interfering with a helicopter coming off the USS Elliot, attempted ramming of rigs used by the South Koreans in their quadrant search, hazardous maneuvering of the Gavril Sarychev and near collision with the USS Callaghan, removing U.S. sonars, setting false pingers in deep international waters, sending Backfire bombers armed with air-to-surface nuclear-armed missiles to threaten U.S. naval units, criss-crossing in front of U.S. combatant vessels, cutting and attempted cuttings of moorings of the Japanese auxiliary vessels, particularly the Kaiko Maru III, and radar lock-ons by a Soviet Kara-class cruiser, the Petropavlosk, and a Kashin-class destroyer, the Odarennyy, targeting U.S. naval vessels. USS Towers, escorting USS Conserver, experienced all of the above interference and was involved in a near-collision with the Odarennyy.

U.S. Task Force 71 After action report map of search area in international waters
According to the ICAO: "The location of the main wreckage was not determined… the approximate position was 46°34′N 141°17′E, which was in international waters." This point is about 41 miles (66 km) from Moneron Island, about 45 miles (72 km) from the shore of Sakhalin and 33 miles (53 km) from the point of attack.
Rear Admiral Walter T. Piotti Jr, commander of Task Force 71 of 7th Fleet, believed the search for KAL 007 in international waters to have been a search in the wrong place and assessed:
"Had TF [task force] 71 been permitted to search without restriction imposed by claimed territorial waters, the aircraft stood a good chance of having been found. No wreckage of KAL 007 was found. However, the operation established, with a 95% or above confidence level, that the wreckage, or any significant portion of the aircraft, does not lie within the probability area outside the 12 nautical miles (22 km) area claimed by the Soviets as their territorial limit."
At a hearing of the ICAO on 15 September 1983, J. Lynn Helms, the head of the Federal Aviation Administration, stated: "The U.S.S.R. has refused to permit search and rescue units from other countries to enter Soviet territorial waters to search for the remains of KAL 007. Moreover, the Soviet Union has blocked access to the likely crash site and has refused to cooperate with other interested parties, to ensure prompt recovery of all technical equipment, wreckage and other material."

Political events

The shootdown happened at a very tense time in U.S.-Soviet relations during the Cold War. The U.S. adopted a strategy of releasing a substantial amount of hitherto highly classified intelligence information in order to exploit a major propaganda advantage over the U.S.S.R. Six hours after the plane was downed, the South Korean government issued an announcement that the plane had merely been forced to land abruptly by the Russians, and that all passengers and crew were safe.
Secretary of State George P. Shultz held a press conference about the incident at 10:45 on 1 September, during which he divulged some details of intercepted Soviet communications and denounced the actions of the Soviet Union.


Listening post at Wakkanai
General Secretary Yuri Andropov, on the advice of Defense Minister Dmitriy Ustinov, but against advice of the Foreign Ministry, initially decided not to make any admission of downing the airliner, on the premise that no-one would find out or be able to prove otherwise.Consequently the TASS news agency reported twelve hours after the shootdown only that an unidentified aircraft, flying without lights, had been intercepted by Soviet fighters after it violated Soviet airspace over Sakhalin. The aircraft had allegedly failed to respond to warnings and "continued its flight toward the Sea of Japan". Some commentators believe that the inept manner in which the political events were handled by the Soviet government was affected by the failing health of Andropov, who was permanently hospitalised in late September or early October 1983.
On 5 September 1983, U.S. President Ronald Reagan condemned the shooting down of the airplane as the "Korean airline massacre", a "crime against humanity [that] must never be forgotten" and an "act of barbarism ... [and] inhuman brutality". The following day, the U.S. ambassador to the United Nations Jeane Kirkpatrick commissioned an audio-visual presentation in the United Nations Security Council, using audio tapes of the Soviet pilots' radio conversations and a map of Flight 007's path in depicting its shooting down. Following this presentation, TASS acknowledged for the first time that the aircraft had indeed been shot down after warnings were ignored. The Soviets challenged many of the facts presented by the U.S., and for the first time, mentioned the presence of a USAF RC-135 surveillance aircraft whose path had crossed that of KAL 007.

On 7 September, Japan and the United States jointly released a transcript of Soviet communications, intercepted by the listening post at Wakkanai, to an emergency session of the United Nations Security Council. US president Reagan issued a National Security Directive stating that the Soviets were not to be let off the hook, and initiating "a major diplomatic effort to keep international and domestic attention focused on the Soviet action". The move was seen by the Soviet leadership of confirmation of the West's bad intentions.
A high level U.S.-Soviet summit, the first in nearly a year, was scheduled for 8 September 1983 in Madrid. The Shultz–Gromyko meeting went ahead, but was overshadowed by the KAL 007 event. It ended acrimoniously, with Shultz stating: "Foreign Minister Gromyko's response to me today was even more unsatisfactory than the response he gave in public yesterday. I find it totally unacceptable." President Reagan ordered the Federal Aviation Administration (FAA) on 15 September 1983 to revoke the license of Aeroflot Soviet Airlines to operate flights to and from the U.S. Aeroflot flights to North America were consequently available only through Canadian and Mexican cities, forcing the Soviet foreign minister to cancel his scheduled trip to the United Nations. Aeroflot service to the U.S. was not restored until 29 April 1986.
An emergency session of the ICAO was held in Montreal. On 12 September 1983, the Soviet Union used its veto to block a United Nations resolution condemning it for shooting down the aircraft.
United Nations Headquarters in New York,.
Shortly after the Soviet Union shot down KAL 007, legislatures in New York and New Jersey denied Soviet aircraft landing rights, in violation of the United Nations Charter that required the host nation to allow all member countries access to the UN. In reaction, TASS and some at the UN raised the question of whether the UN should move its headquarters from the United States. Charles Lichenstein, acting US permanent representative to the UN under Ambassador Kirkpatrick, responded, "We will put no impediment in your way. The members of the US mission to the United Nations will be down at the dockside waving you a fond farewell as you sail off into the sunset." Administration officials were quick to announce that Lichenstein was speaking only for himself.
In the Cold War context of Operation RYAN, the Strategic Defence Initiative, Pershing II missile deployment in Europe, and the upcoming Exercise Able Archer, the Soviet Government perceived the incident with the Korean airliner to be a portent of war. The Soviet hierarchy took the official line that KAL Flight 007 was on a spy mission, as it "flew deep into Soviet territory for several hundred kilometres, without responding to signals and disobeying the orders of interceptor fighter planes". They claimed its purpose was to probe the air defences of highly sensitive Soviet military sites in the Kamchatka Peninsula and Sakhalin Island. The Soviet government expressed regret over the loss of life, but offered no apology and did not respond to demands for compensation. Instead, the U.S.S.R. blamed the CIA for this "criminal, provocative act", and argued that the U.S. case was incredible:
"Today, when all versions have been viewed from all possible angles, when leading specialists, including pilots who have flown Boeings for thousands of hours, have declared that three computers could not break down all at once, and neither could five radio transmitters, there can be no doubt as to the intentions of the intruder plane. The Soviet pilots who intercepted the aircraft could not have known that it was a civilian plane. It was flying without the navigation lights, in conditions of poor visibility and did not respond to radio signals."


NTSB
Since the aircraft had departed from US soil and US nationals had died in the incident, the National Transportation Safety Board (NTSB) was legally required to investigate. On the morning of 1 September, the NTSB chief in Alaska, James Michelangelo, received an order from the NTSB in Washington at the behest of the State Department requiring all documents relating to the NTSB investigation to be sent to Washington, and notifying him that the State Department would now conduct the investigation. The US State Department, after closing the NTSB investigation on the grounds that it was not an accident, pursued an ICAO investigation instead. Commentators such as Johnson point out that this action was illegal, and that in deferring the investigation to the ICAO, the Reagan administration effectively precluded any politically or militarily sensitive information from being subpoenaed that might have embarrassed the administration or contradicted its version of events. Unlike the NTSB, ICAO can subpoena neither persons nor documents and is dependent on the governments involved—in this incident, the United States, the Soviet Union, Japan, and South Korea—to supply evidence voluntarily.

Initial ICAO investigation (1983)
ICAO had only one experience of investigation of an air disaster prior to the KAL 007 shootdown. This was the incident of 21 February 1973, when Libyan Arab Airlines Flight 114 was shot down by Israeli F-4 jets over the Sinai Peninsula. ICAO convention required the state in whose territory the accident had taken place (the U.S.S.R.) to conduct an investigation together with the country of registration (South Korea), the country whose air traffic control the aircraft was flying under (Japan), as well as the aircraft's manufacturer (Boeing).
The ICAO investigation did not have the authority to compel the states involved to hand over evidence, instead having to rely on what they voluntarily submitted. Consequently, the investigation did not have access to sensitive evidence such as radar data, intercepts, ATC tapes, or the Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR) (whose discovery the U.S.S.R. had kept secret). A number of simulations were conducted with the assistance of Boeing and Litton (the manufacturer of the navigation system).
The ICAO released their report 2 December 1983, which concluded that the violation of Soviet airspace was accidental: One of two explanations for the aircraft's deviation was that the autopilot had remained in HEADING hold instead of INS mode after departing Anchorage. They postulated that this inflight navigational error was caused by either the crew's failure to select INS mode, or the inertial navigation's not activating when selected, because the aircraft was already too far off track. It was determined that the crew did not notice this error or subsequently perform navigational checks, that would have revealed that the aircraft was diverging further and further from its assigned route. This was later deemed to be caused by a "lack of situational awareness and flight deck coordination".
The report included a statement by the Soviet Government claiming "no remains of the victims, the instruments or their components or the flight recorders have so far been discovered".This statement was subsequently shown to be untrue by Boris Yeltsin's release in 1993 of a November 1983 memo from KGB head Viktor Chebrikov and Defence Minister Dmitry Ustinov to Yuri Andropov. This memo stated "In the third decade of October this year the equipment in question (the recorder of in-flight parameters and the recorder of voice communications by the flight crew with ground air traffic surveillance stations and between themselves) was brought aboard a search vessel and forwarded to Moscow by air for decoding and translation at the Air Force Scientific Research Institute." The Soviet Government statement would further be contradicted by Soviet civilian divers who later recalled that they viewed wreckage of the aircraft on the bottom of sea for the first time on 15 September, two weeks after the plane had been shot down.
Following publication of the report, the ICAO adopted a resolution condemning the Soviet Union for the attack. Furthermore, the report led to a unanimous amendment in May 1994 to the Convention on International Civil Aviation that defined the use of force against civilian airliners in more detail. The amendment to section 3(d) reads in part: "The contracting States recognize that every State must refrain from resorting to the use of weapons against civil aircraft in flight and that, in case of interception, the lives of persons on board and the safety of aircraft must not be endangered."

U.S. Air Force radar data
It is customary for the Air Force to impound radar trackings involving possible litigation in cases of aviation accidents. In the civil litigation for damages, the United States Department of Justice explained that the tapes from the Air Force radar installation at King Salmon, Alaska pertinent to KAL 007's flight in the Bethel area had been destroyed and could therefore not be supplied to the plaintiffs. At first Justice Department lawyer Jan Van Flatern stated that they were destroyed 15 days after the shootdown. Later, he said he had "misspoken" and changed the time of destruction to 30 hours after the event. A Pentagon spokesman concurred, saying that the tapes are re-cycled for reuse from 24–30 hours afterwards; the fate of KAL 007 was known inside this timeframe.

Interim developments
Boris Yeltsin
Hans Ephraimson-Abt, whose daughter Alice Ephraimson-Abt had died on the flight, chaired the American Association for Families of KAL 007 Victims. He single-handedly pursued three U.S. administrations for answers about the flight, flying to Washington 250 times and meeting with 149 State Department officials. Following the dissolution of the U.S.S.R., Ephraimson-Abt persuaded U.S. Senators Ted Kennedy, Sam Nunn, Carl Levin, and Bill Bradley to write to the Soviet President, Mikhail Gorbachev requesting information about the flight. Glasnost reforms in the same year brought about a relaxation of press censorship; consequently reports started to appear in the Soviet press suggesting that the Soviet military knew the location of the wreckage and had possession of the flight data recorders. On 10 December 1991, Senator Jesse Helms of the Committee on Foreign Relations, wrote to Boris Yeltsin requesting information concerning the survival of passengers and crew of KAL 007 including the fate of Congressman Larry McDonald.
On 17 June 1992, President Yeltsin revealed that after the 1991 Soviet coup d'état attempt, concerted attempts were made to locate Soviet-era documents relating to KAL 007. He mentioned the discovery of "a memorandum from K.G.B. to the Central Committee of the Communist Party," stating that a tragedy had taken place and adding that there are documents "which would clarify the entire picture." Yeltsin said the memo continued to say that "these documents are so well concealed that it is doubtful that our children will be able to find them." On September 11, 1992, Yeltsin officially acknowledged the existence of the recorders, and promised to give the South Korean government a transcript of the flight recorder contents as found in KGB files.
In October 1992, Hans Ephraimson-Abt led a delegation of families and U.S. State Department officials to Moscow at the invitation of President Yeltsin. During a state ceremony at St. Catherine's Hall in the Kremlin, the KAL family delegation was handed a portfolio containing partial transcripts of the KAL 007 cockpit voice recorder, translated into Russian, and documents of the Politburo pertaining the tragedy.
In November 1992, President Yeltsin handed the two recorder containers to Korean President Roh Tae-Woo, but not the tapes themselves. The following month, the ICAO voted to reopen the KAL 007 investigation in order to take the newly released information in account. The tapes were handed to ICAO in Paris on 8 January 1993. Also handed over at the same time were tapes of the ground to air communications of the Soviet military.[119] The tapes were transcribed by the Bureau d'Enquêtes et d'Analyses pour la sécurité de l'Aviation Civile (BEA) in Paris in the presence of representatives from Japan, The Russian Federation, South Korea, and the United States.
A 1993 official enquiry by the Russian Federation absolved the Soviet hierarchy of blame, determining that the incident was a case of mistaken identity. On 28 May 1993, the ICAO presented its second report to the Secretary-General of the United Nations.

Soviet memoranda
In 1992, Russian president Boris Yeltsin disclosed five top-secret memos dating from a few weeks after of the downing of KAL 007 in 1983. The memos contained Soviet communications (from KGB Chief Viktor Chebrikov and Defence Minister Dmitry Ustinov to Premier Yury Andropov) that indicated that they knew the location of KAL 007's wreckage while they were simulating a search and harassing the American Navy; they had found the sought-after cockpit voice recorder on 20 October 1983 (50 days after the incident), and had decided to keep this knowledge secret, the reason being that the tapes could not unequivocally support their firmly held view that KAL 007's flight to Soviet territory was a deliberately planned intelligence mission.
“ Simulated search efforts in the Sea of Japan are being performed by our vessels at present in order to dis-inform the U.S. and Japan. These activities will be discontinued in accordance with a specific plan...
Therefore, if the flight recorders shall be transferred to the western countries their objective data can equally be used by the U.S.S.R. and the western countries in proving the opposite view points on the nature of the flight of the South Korean airplane. In such circumstances a new phase in anti-Soviet hysteria cannot be excluded.
In connection with all mentioned above it seems highly preferable not to transfer the flight recorders to the International Civil Aviation Organization (ICAO) or any third party willing to decipher their contents. The fact that the recorders are in possession of the U.S.S.R. shall be kept secret...
As far as we are aware neither the U.S. nor Japan has any information on the flight recorders. We have made necessary efforts in order to prevent any disclosure of the information in future.
Looking to your approval.
”
—D. Ustinov, V. Chebrikov (photo) December 1983"


The Mikhail Merchink. Lead Soviet vessel in simulated search
The third memo acknowledges that analysis of the recorder tapes showed no evidence of the Soviet interceptor attempting to contact KAL 007 via radio nor any indication that the KAL 007 crew was aware of warning shots being fired.
"However in case the flight recorders shall become available to the western countries their data may be used for: Confirmation of no attempt by the intercepting aircraft to establish a radio contact with the intruder plane on 121.5 MHz and no tracers warning shots in the last section of the flight"
That the Soviet search was simulated (while knowing the wreckage lay elsewhere) also is suggested by the article of Mikhail Prozumentshchikov, Deputy Director of the Russian State Archives of Recent History, commemorating the twentieth anniversary of the airplane's shooting down. Commenting on the Soviet and American searches: "Since the U.S.S.R., for natural reasons, knew better where the Boeing had been downed...it was very problematical to retrieve anything, especially as the U.S.S.R. was not particularly interested".

Revised ICAO report (1993)
On 18 November 1992, Russian President Boris Yeltsin, in a goodwill gesture to South Korea during a visit to Seoul to ratify a new treaty, released both the flight data recorder (FDR) and cockpit voice recorder (CVR) of KAL 007. Initial South Korean research showed the FDR to be empty and the CVR to have an unintelligible copy. The Russians then released the recordings to the ICAO Secretary General. The ICAO report continued to support the initial assertion that KAL 007 accidentally flew in Soviet airspace, after listening to the flight crew's conversations recorded by the CVR.


A typical digital flight data recorder and cockpit voice recorder
In addition, the Russian Federation released "Transcript of Communications. U.S.S.R. Air Defence Command Centres on Sakhalin Island" transcripts to ICAO—this new evidence triggered the revised ICAO report in 1993 "The Report of the Completion of the Fact Finding Investigation", and is appended to it. These transcripts (of two reels of tape, each containing multiple tracks) are time specified, some to the second, of the communications between the various command posts and other military facilities on Sakhalin from the time of the initial orders for the shootdown and then through the stalking of KAL 007 by Maj. Osipovoich in his Sukhoi 15 interceptor, the attack as seen and commented on by General Kornukov, Commander of Sokol Air Base, down the ranks to the Combat Controller Lt. Col. Titovnin, the post-attack flight of KAL 007 until it had reached Moneron Island, the descent of KAL 007 over Moneron, the initial Soviet SAR missions to Moneron, the futile search of the support interceptors for KAL 007 on the water, and ending with the debriefing of Osipovich on return to base. Some of the communications are the telephone conversations between superior officers and subordinates and involve commands to them, while other communications involve the recorded responses to what was then being viewed on radar tracking KAL 007. These multi-track communications from various command posts telecommunicating at the same minute and seconds as other command posts were communicating provide a "composite" picture of what was taking place.
The data from the CVR and the FDR revealed that the recordings broke off after the first minute and 44 seconds of KAL 007's post missile detonation 12 minute flight. The remaining minutes of flight would be supplied by the Russia 1992 submission to ICAO of the real-time Soviet military communication of the shootdown and aftermath. The fact that both recorder tapes stopped exactly at the same time 1 minute and 44 seconds after missile detonation (18:38:02 GMT) without the tape portions for the more than 10 minutes of KAL 007's post detonation flight before it descended below radar tracking (18:38 GMT) finds no explanation in the ICAO analysis, "It could not be established why both flight recorders simultaneously ceased to operate 104 seconds after the attack. The power supply cables were fed to the rear of the aircraft in raceways on opposite sides of the fuselage until they came together behind the two recorders."

Passenger pain and suffering
Passenger pain and suffering was an important factor in determining the level of compensation that was paid by Korean Air Lines.
Fragments from the proximity fused R-98 medium range air-to-air missile exploding 50 metres (160 ft) behind the tail caused punctures to the pressurized passenger cabin. When one of the flight crew radioed Tokyo Area Control one minute and two seconds after missile detonation his breathing was already "accentuated", indicating to ICAO analysts that he was speaking through the microphone located in his oxygen mask, "Korean Air 007 ah... We are... Rapid compressions. Descend to 10,000."
Two expert witnesses testified at a Court of Appeals trial on the issue of pre-death pain and suffering. Captain James McIntyre, an experienced Boeing 747 pilot and aircraft accident investigator, testified that shrapnel from the missile caused rapid decompression of the cabin, but left the passengers sufficient time to don oxygen masks: "McIntyre testified that, based upon his estimate of the extent of damage the aircraft sustained, all passengers survived the initial impact of the shrapnel from the missile explosion. In McIntyre's expert opinion, at least 12 minutes elapsed between the impact of the shrapnel and the crash of the plane, and the passengers remained conscious throughout."


 Korean Air Lines Flight 007 alternate theories
Flight 007 has been the subject of ongoing controversy and has spawned a number of conspiracy theories. Many of these are based on the suppression of evidence such as the flight data recorders, unexplained details such as the role of a USAF RC-135 surveillance aircraft, or merely Cold War disinformation and propaganda.

Aftermath

"The Tower of Prayer", a monument to KAL 007 at Cape Sōya, Japan
The FAA temporarily closed Airway R-20, the air corridor that Korean Air Flight 007 was meant to follow, on 2 September. Airlines fiercely resisted the closure of this popular route, the shortest of five corridors spanning Alaska and the Far East. It was therefore reopened on 2 October after safety and navigational aids were checked.
NATO had decided, under the impetus of the Reagan administration, to deploy Pershing II and cruise missiles in West Germany. This deployment would have placed missiles just 6–10 minutes striking distance from Moscow. Support for the deployment was wavering and it looked doubtful that it would be carried out. When the Soviet Union shot down Flight 007, the U.S. was able to galvanize enough support at home and abroad to enable the deployment to go ahead.
The unprecedented disclosure of the communications intercepted by the United States and Japan revealed a considerable amount of information about their intelligence systems and capabilities. National Security Agency director Lincoln D. Faurer commented: "...as a result of the Korean Air Lines affair, you have already heard more about my business in the past two weeks than I would desire...For the most part this has not been a matter of unwelcome leaks. It is the result of a conscious, responsible decision to address an otherwise unbelievable horror." Changes that the Soviets subsequently made to their codes and frequencies reduced the effectiveness of this monitoring by 60%.
The U.S. KAL 007 Victims' Association, under the leadership of Hans Ephraimson-Abt, successfully lobbied U.S. Congress and the airline industry to accept an agreement that would ensure that future victims of airline accidents would be compensated quickly and fairly by increasing compensation and lowering the burden of proof of airliner misconduct. This legislation has had far-reaching effects for the victims of subsequent aircraft disasters.
The U.S. decided to utilize military radars to extend air traffic control radar coverage from 200 miles (320 km) to 1,200 miles (1,900 km) out from Anchorage. In 1986, the United States, Japan and the Soviet Union set up a joint air traffic control system to monitor aircraft over the North Pacific, thereby giving the Soviet Union formal responsibility to monitor civilian air traffic, and setting up direct communication links between the controllers of the three countries.
Ronald Reagan announced on 16 September 1983 that the Global Positioning System (GPS) would be made available for civilian use, free of charge, once completed in order to avert similar navigational errors in future. Furthermore, the interface of the autopilot used on large airlines was modified to make it more obvious whether it is operating in HEADING mode or INS mode.
Alvin Snyder, the director of worldwide television for the United States Information Agency, was the producer of the video shown to the U.N. Security Council on 6 September 1983. In an article in Washington Post on 1 September 1996, he stated that he had been given only limited access to the transcripts of the Russian communication when he produced the video in 1983. When he received full insight into the Russian transmissions in 1993, he says he realised that: "The Russians believed the plane to be a RC-135 reconnaissance plane" and that "Osipovich (the Russian fighter pilot) could not identify the plane" and "That he fired warning cannons and tipped his wings, an international signal to force the plane to land".Some of these statements were contradicted by the pilot in an interview with the New York Times, in which he confirmed that he did fire warning shots, but that they would not have been visible as they were not tracers.
In a 15 March 2001 interview, Valeri Kamenski, then Commander of the Soviet Far East Military District Air Defense Force and direct superior to Gen. Kornukov, opined that such a shootdown of a civilian passenger plane could not happen again in view of the changing political conditions and alliances. In this interview, Kaminski stated, “It is still a mystery what happened to the bodies of the crew and passengers on the plane. According to one theory, right after the rocket’s detonation, the nose and tail section of the jumbo fell off and the mid fuselage became a sort of wind tunnel so the people were swept through it and scattered over the surface of the ocean. Yet in this case, some of the bodies were to have been found during the search operations in the area. The question of what actually happened to the people has not been given a distinct answer.”

Popular culture

The song "Murder In The Skies" on UK blues-rock guitarist Gary Moore's 1984 album Victims Of The Future was a protest against the shooting down of Korean Air Lines Flight 007.
Lee Greenwood has stated that he wrote the song "God Bless the USA" in response to his feelings about the shooting down of Korean Air Lines Flight 007. "The song just about wrote itself," Greenwood said in the book God Bless the USA (by Greenwood and Gwen McLin). "The words seemed to flow naturally from the music, and came out with total honesty. They were an expression of my feelings of pride. To me, America seemed just like a rookery, a place where we have a chance to grow, unmolested and free."
Two television movies were produced about the incident; both films were produced before the fall of the Soviet Union allowed access to archives:
Shootdown (1988), starring Angela Lansbury, John Cullum, and Kyle Secor, was based on the book of the same title by R.W. Johnson, about the efforts of Nan Moore (Lansbury), the mother of a passenger, to get answers from the US and Russian governments.
The British Granada Television documentary drama Coded Hostile, screened on 7 September 1989, detailed the US military and governmental investigation, highlighting the likely confusion of Flight 007 with the USAF RC-135 in the context of routine US SIGINT/COMINT missions in the area. Written by Brian Phelan and directed by David Darlow, it starred Michael Murphy, Michael Moriarty, and Chris Sarandon. It was screened by HBO in the United States under the title Tailspin – Behind the Korean Airliner Tragedy on 20 August 1989. An updated version of Coded Hostile was screened in the UK on 31 August 1993, incorporating details of the 1992 UN investigation.
The Discovery Channel documentary series Unsolved History featured this incident.
