Planes have to go through check-lists before they leave, so unless the government also paid off all the air traffic controllers, pilots, luggage carriers and other witnesses there at the airport that day I don't see how it could happen.Like I've said before, in order for the government to execute this massive plane it would take a miracle. There is absoutely no way they could keep this secret. This isn't like any shady buisness that happens behind closed doors, this is in the public eye and all over TV. Too many people and too many cameras for them to pull this off.
