After the second World Trade Center crash at 9:03 a.m., air traffic controllers at the FAA’s New York Center are told by their supervisors to watch for airplanes whose speed indicates that they are jets, but which either are not responding to commands or have disabled their transponders. Controllers in Washington receive a similar briefing, which will help them pick out hijacked planes more quickly. [New York Times, 9/13/2001] Whether controllers at other FAA air traffic control centers receive similar instructions at this time is unclear, but those at its Indianapolis Center, which is handling Flight 77, are apparently not informed by their supervisors of the unfolding crisis.
