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
