(8:58 a.m.-9:03 a.m.) September 11, 2001: Controllers Watch Flight 175 Descending 10,000 Feet per Minute

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, 2005] From 8:58 a.m., Flight 175 is constantly descending toward New York. [National Transportation Safety Board, 2/19/2002 ] 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, 2005] 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).
