Technically speaking, at least some of the crewmembers were killed during the initial takeover and it is quite likely other crew, passengers and hijackers died during the struggle before the crash.
The way it is worded implies that the the passengers were responsible for the crash. I object. The plane was going to crash anyway. All the heroic passengers did was change the crash site from the Capitol to a pasture.
ALL?
The killers brought the plane down sooner because they shit their Islamic ass's during the uprising that's why!
"United 93" makes that unmistakably clear.
Go see it -- unless one has an "anger management" problem...
