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 pdf file; The Learning Channel, 8/20/2006] 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, 8/20/2006] 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).

Flight 175, now in descent, briefly levels off at 28,500 feet and starts turning northeast. A minute later, it resumes its descent as it heads toward New York City. [National Transportation Safety Board, 2/19/2002 pdf file; 9/11 Commission, 8/26/2004, pp. 22]

Air traffic controllers at the FAA’s New York Center who are watching Flight 175 on the radar screen (see (8:57 a.m.-9:03 a.m.) September 11, 2001) see the aircraft descending at an astonishing rate of up to 10,000 feet per minute. [The Learning Channel, 8/20/2006] From 8:58 a.m., Flight 175 is constantly descending toward New York. [National Transportation Safety Board, 2/19/2002 pdf file] One of the New York Center controllers, Jim Bohleber, is looking at his radar scope and calls out the plane’s rate of descent every 12 seconds, each time the screen updates, saying: “It’s six thousand feet a minute. Now it’s eight. Now ten.” [Newsday, 9/10/2002; Vanity Fair, 8/1/2006] Dave Bottiglia, the controller responsible for monitoring Flight 175, will later comment that 10,000 feet per minute is “absolutely unheard of for a commercial jet. It is unbelievable for the passengers in the back to withstand that type of force as they’re descending. [The hijackers are] actually nosing the airplane down and doing what I would call a ‘power dive.’” [The Learning Channel, 8/20/2006] While Flight 175 is in this rapid descent, it heads directly into the paths of several other aircraft, and narrowly avoids a mid-air collision with flight Midex 7 (see (9:01 a.m.) September 11, 2001).
