9:01 a.m. September 11, 2001: FAA’s New York Center Informs TRACON Controllers about Flight 175

The FAA’s New York Center contacts the New York Terminal Radar Approach Control (TRACON) and asks for help in locating Flight 175. Different air traffic controllers scan different altitudes, and TRACON controllers only deal with low-flying planes. These controllers have remained uninformed about the fate of Flight 11 until about now. “We had 90 to 120 seconds; it wasn’t any 18 minutes,” one controller wil later recall, referring to the actual elapsed time between the two crashes. Another controller will say of Flights 11 and 175: “They dove into the airspace. By the time anybody saw anything, it was over.” [New York Times, 9/13/2001; 9/11 Commission, 6/17/2004 ]
