The FAA had read Delta 1989 to be in Cleveland airspace and ordered Cleveland Center to watch for Delta 1989 as a suspected hijacking . A Cleveland controller thought he heard " Get out of here " and " We have a bomb on board " coming from Delta 1989 . The Delta pilot denied any cockpit intrusion and stated that everyone on board was fine . It was later confirmed that the transmission had come from United Airlines Flight 93 , which was in the same vicinity as Delta 1989 , and would later crash into a field in Shanksville , Pennsylvania , after the passengers and crew revolted against the hijackers . The NORAD Northeast Air Defense Sector ( NEADS ) became aware of Delta 1989 right after the crash of American Airlines Flight 77 into the Pentagon at 9:37 AM when Boston Center called NEADS at 9:41 AM EDT and told NEADS of the suspicions regarding Delta 1989 . At 9:42 AM EDT , the FAA ordered all aircraft in flight to land at the nearest airport . NEADS dispatched fighter aircraft from Ohio and Michigan to intercept the flight , though Delta 1989 never turned off its transponder and NEADS never lost radar contact with the aircraft . NEADS , the FAA Herndon Command Center , and Cleveland Center tracked Delta 1989 until its eventual landing
