It would help if you got your facts right. UT-772 happened nine months after Lockerbie not before
I got my choronolgy mixed up - apologies.
As I've said I believe any factual statement in the AAIB report but not the written padding,
Again I ask what qualifies you to seperate factual statement from written padding?
As for explosive decompressions. there was only one,
O Really? I am not contesting there was only one, there was only one pressurised container, of course there was only one.
when the pressure hull of Pan Am 103 was breached when the IED went off. The cab air was have blown out of the aircraft in rather less than half a second.
The second explosion went off 14 seconds later, but the aircraft was in the dark, or with emergency lighting only and diving at an angle of rather more than 45 degrees. It took place at 19000'
How do you know?
Your website claims that this is so because some of the wreckage from PA103 was never found, and that this was consumed by the brisant explosion caused by the 2nd bomb. Is that correct?
The mid air breakup of PA103 is documented by the AAIB report as follows.
(I'm paraphrasing, please do go and check the report to ensure I am not mistaken here)
21st December 1988 PA103 levels off at cruising altitude of 31000' at 19:56 at about 19:03 during radio transmission of oceanic clearance from ATC the last radar return is noted, very shortly after this the IED detonates.
The initial blast shockwave punches a small hole in the luggage container, and a larger hole approximately 20" by 10" in the outer skin of the aircraft. Pressurised hull integrity is still holding at this point, the cargo hold not being pressurised.
A fraction of a second later the blast wave(the actual hot gases of the explosion) blows a much larger hole in the side of the aircraft, the petalled starburst hole near the detonation point as well as probably causing other ruptures at other points in the aircraft, hull integrity is lost and the aircraft depressurises.
The combined explosive forces of the blast shockwaves break control cables and apply inputs to some control surfaces of the aircraft causing it to turn left and point downwards at approximately 45degrees.
2-3 seconds after the explosion with the aircraft pointed downwards and rolled to the left the forces of the explosion combined with the decompression are tearing the aircraft apart along it's weakest points (mostly where it is rivetted together) at cruising speed such an aircraft travels at about 500mph (434Knots) so there is the added force of a 500mph wind outside the aircraft to aid in the destruction. At about this point in time the flight deck and a portion of the front of the aircraft detaches, it strikes #3 engine, detaching it from the wing.
We know this must be the sequence of breakup because of analyisis of where seperate pieces of the aircraft fell.
The aircraft is now pitched nose down, it's accelerating as it falls, it is missing an engine and has no nose. 500mph+ winds are tearing through the aircraft as it falls and these forces break apart the airframe further. At about 19000' the aircraft is descending vertically, still accelerating and the tail, which was struck by debris from the initial blast, and from aircraft contents released by the initial blast, breaks free. No explosive residues are found in the tail structure, this completely rules out a 2nd explosion in the tail area.
Aside from the area around the first IED no explosion damage was detected anywhere else in the aircraft.
The AAIB are not entirely sure what caused the tail to break off, they do strongly suspect the large forces being applied to the airframe from air resistance as having a major part to play in it however (flutter).
As the aircraft continues to fall vertically it breaks up even more, once the tail is gone it begins to spin (presumably as a result of the stuck control surfaces on the wings that were initially responsible for the immediate roll to the left early on) this shears off the remaining engines. At about 9000' the aircraft is almost totally disintegrated.
It strikes the ground approximately 45 seconds after the initial blast.
