Answer 1

If I understand what your saying, flight 93 was the one that crashed in the middle of nowhere and disintegrated on impact killing everybody on board

Answer 2

On the morning of September 11, 2001 four different airliners were hi-jacked by members of Al-Queda. The first two planes, American Airlines Flight 11 and United Airlines Flight 175, were flown into the two towers of the World Trade Center in New York City. A third plane, American Airlines Flight 77, hit the western side of the Pentagon in Washington, D.C. However, the fourth flight, United Flight 93, never reached its intended target as the crew and passegers on the plane fought against the hijackers. The plane crashed in a field in rural Pennsylvania. The actions of those on Flight 93 saved many lives.
