Minutes before the 10 a.m. crash, an emergency dispatcher in Pennsylvania received a cell phone call from a man who said he was a passenger locked in a bathroom aboard United Flight 93. The man repeatedly said the call was not a hoax, said dispatch supervisor Glenn Cramer in neighboring Westmoreland County. "We are being hijacked, we are being hijacked!" Cramer quoted the man from a transcript of the call. The man told dispatchers the plane "was going down. He heard some sort of explosion and saw white smoke coming from the plane and we lost contact with him," Cramer said.
