(8:51 a.m.) September 11, 2001: Air Traffic Controller Watches Flight 175 Suddenly Climb 3,000 Feet, NEADS Not Contacted

The air traffic controller at the FAA’s New York Center who is responsible for monitoring Flight 175 sees the now-hijacked plane on his radar screen making a sharp turn (see (8:50 a.m.) September 11, 2001), and is astonished as it rapidly climbs 3,000 feet. [National Transportation Safety Board, 2/19/2002 ; The Learning Channel, 2005] Around this time, the controller, Dave Bottiglia, first notices that Flight 175’s transponder code has changed (see 8:51 a.m.-8:53 a.m. September 11, 2001). [9/11 Commission, 8/26/2004, pp. 21 ] As he will later recall: “As I’m watching, United 175 makes a hard left-hand turn and starts climbing. Not only did he make a sharp turn, but he also climbed 3,000 feet in a matter of approximately one minute, which is a very fast rate of climb.” Bottiglia will add, “This is something that we have never seen before.” He immediately turns to the manager at the New York Center and says, “I believe I just lost United 175.” [The Learning Channel, 2005] Yet, according to the 9/11 Commission, the center does not alert NORAD’s Northeast Air Defense Sector (NEADS) to Flight 175 until 9:03 a.m. (see (9:03 a.m.) September 11, 2001).
