The 9/11 hijackers hijacked the planes because Osama bin Ladin and the fellow members of al Quada are Muslims. That means that they believe in Allah. (or God) They hijacked planes because they have 24,000 gallons of jet fuel in the plane! They bought little knives that anybody can buy from a hardware store so nobody would think that they would hijack a plane and kill about 4,000 people!
The total of lives lost on board the 4 hijacked planes, not including the hijackers, were 246
Actually, all of the hijackers that flew the planes on 9/11/01 were aliens. Not one of the 19 hijackers was a US citizen. They didn't come from space, they came from various other Earth countries.
