Question

Answer 1

There were 2 planes that crashed into both buildings. One was American Airlines Flight 11 from  Logan International Airport in Boston, Massachusetts which hit the north tower. The second was also an American Airlines flight 77 which left from Washington Dulles International Airport, near Washington, D.C. and then hit the south tower.

Answer 2

I believe it was from Massachussetts, and I think it was American Airlines.
