After flying west near Cleveland, Ohio, the flight turned back and started fliying toward Washington, D.C or possibly Camp David, Maryland. Family members related to those onboard received cellular phone calls that the plane had been hijacked and were asked for information concerning the other airplanes that had been hijacked. A Pennsylvania police department received a 911 call from a man who claimed to be locked in the airplane's lavatory and screamed that the flight had been hijacked.

After witnessing the murder of one flight attendant and an attack on another, several men onboard the flight decided to fight back. They were aware of the fate of the two planes that had crashed into the World Trade Center and refused to be party to another such attack.

As the plane flew over Pennsylvania, it was seen to be flying at low altitude (approximately 2000 feet). Witnesses saw it make a sharp left turn, then a sharp right turn. Another witness then saw it flying even lower (approximately 500 feet). It seemed to be gaining altitude and then dive to the right. Another witness picks up from there and saw it dive behind a hill. Both witnesses felt the concushion of the crash and then smoke. Another witness saw a fireball after it disappeared below the treeline.
