The CVR then recorded a very loud sound for a fraction of a second (0.117 second) on all channels immediately before the recording ended. NTSB AAR 00003
 
"The CVR revealed normal communication before the decompression. At 0209:09:2 HST, a loud bang could be heard on the CVR. The loud bang was about 1.5 seconds after a "thump" was heard on the CVR for which one of the flightcrew made a comment. The electrical power to the CVR was lost for approximately 21.4 seconds following the loud bang. The CVR returned to normal operation at 0209:29 HST, and cockpit conversation continued to be recorded in a normal manner.

"The CVR tape was listened to for its full duration and there was no indication of anything abnormal with the aircraft, or unusual crew behaviour. The tape record ended, at 19:02:50 hrs +- second, with a sudden loud sound on the CAM channel followed almost immediately by the cessation of recording whilst the crew were copying their transatlantic clearance from Shanwick ATC."
UK AAIB Report 2/90 Page 15
"From the CVR and DFDR, AI 182 was proceeding normally en route from Montreal to London at an altitude of 31,000 feet and an indicated airspeed of 296 knots when the cockpit area microphone detected a sudden loud sound. The sound continued for about 0.6 seconds, and then almost immediately, the line from the cockpit area microphone to the cockpit voice recorder at the rear of the pressure cabin was most probably broken. This was followed by a loss of electrical power to the recorder."

    Four early model Boeing 747s (747-100 and 747-200) have experienced a sudden explosive decompression which have resulted in fatalities. The sudden loud sound of the initial event was recorded on the cockpit voice recorders (CVR) and after analysis a bomb sound was ruled out. The model for all of the other three accidents is United Airlines Flight 811 which experienced the same sudden loud sound but was able to land largely intact. The evidence United Airlines Flight 811 matches in many ways the evidence of the other three.

    There were no bombs on Air India Flight 182 and Pan Am Flight 103. There were no bombers, no crimes, no criminals, and no conspiracies. There was and is a mechanical problem which exists to this day, aging and failing Poly X wiring which exploits design errors of non plug cargo doors and omitted midspan locking sectors allowing an explosive decompression when the forward cargo door ruptures open in flight. United Airlines Flight 811 is the accident that matches the others.
    There are no conspiracies amongst the agencies, just well meaning people acting in their own perceived best interests.
