What happened in 911?

explain in details please ..

On september 11, 2001 a terrorist group named Al Queda based in afgahnistan hijacked 3 sets of commercial planes, one directed at the twin towers, one at the pentagon, and one at the white House. So when the first plane hit, in the twin towers everyone was shocked and didnt know how to react then people realized that this was a terroist attack and many died. Once news broke out, the passangers on the other planes fought the terrorists in an attempt to steer the plane away from hitting the pentagon. Once these events were over, the Us lead a search party for the group responsibles leader Osama Bin Laden and executed him. They also enforced strong airline laws and the war on terrorism also occured.
