Well experts disagree with you, his seat was over the main fuel tank and if the fire had managed to catch the wall of the plane on fire according to “experts” it most likely would have managed to explode that tank... and as to why AQ would take credit.. come on now, they love to take credit where credit is due and this is coming from one of the real AQ websites (per Catherine Heridge Fox News)... and Yemen is now the Afghanistan of the region where AQ is concerned...
Perhaps it would have. If. If. If. Maybe.
But then again, no one should have been able to sneak PETN on board to begin with.
for 8 years while in the militiary I world with many kinds of explosives and I can honestly say that the amount and what he had would have blown an hole in that plane and would have killed everyone on board
