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.
