The above aircraft was an: (1) aged (2) high flight time (3) early model Boeing 747 (4) which took off in darkness (5) running late (6) and shortly after takeoff (7) experienced a sudden initial event in the forward cargo hold which left a (8) short (9) sudden (10) loud (11) sound on the cockpit voice recorder, an (12) abrupt (13) power cut to the flight data recorder, (14) foreign object damage to starboard engines #3 and (15) #4, (16) more severe inflight damage on starboard side, (17) nine never recovered bodies, (18) torn off skin in forward cargo door area on starboard side, (19) longitudinal break at midline of the forward cargo door at midspan latch, (20) outward peeled skin on upper forward fuselage, (21) vertical fuselage tear lines forward of the wing and aft of forward cargo door, and (22) destruction initially thought to be have been caused by a bomb.
The Air Accidents Investigation Branch of UK has given the probable cause for Pan Am 103 as the explosion of an improvised explosive device in the forward cargo hold. The probable cause of UAL 811 was the inadvertent opening of the forward cargo door inflight as described in NTSB AAR 92/02 from which all of the above twenty two significant observations were drawn. The twenty two significant observations about PA 103 were drawn from UK AAIB 2/90 released statements and photographs of wreckage reconstruction. barry@corazon.com www.corazon.com
