US Army Lieutenant General Michael A. Canavan is appointed associate administrator for civil aviation security at the Federal Aviation Administration (FAA), a position that includes being the “hijack coordinator” (see 8:30 a.m. September 11, 2001). [Federal Aviation Administration, 11/2000] In early 1998, Canavan participated in reviewing a CIA plan to capture Osama bin Laden in Afghanistan. He was then the commander of the Joint Special Operations Command (JSOC), which oversees the military’s counterterrorism operations and covert missions. He objected to the plan, saying it was too complicated for the CIA and “out of their league.” [9/11 Commission, 7/24/2004, pp. 113] The plan was later canceled (see 1997-May 29, 1998). It is not known if Canavan’s appointment at the FAA is related to his prior involvement in counterterrorism or to any intelligence that al-Qaeda might target civil aviation. He will leave the post in October 2001, after only 10 months, reportedly after clashing with other FAA officials. [Los Angeles Times, 10/13/2001]

FAA radar displays begin showing that a growing number of international flights approaching America are transmitting warning codes from their transponders. [Spencer, 2008, pp. 196-197]
Airspace Shut Down - At around 9:45 a.m., the FAA shut down US airspace and ordered all aircraft to land (see (9:45 a.m.) September 11, 2001). Shortly afterwards, Canada took similar action. However, international flights that are over the oceans and approaching America are getting low on fuel. As their crews establish radio contact with air traffic controllers, they are told that American airspace is closed. Many of the worried pilots dial emergency codes into their transponders. [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; 9/11 Commission, 7/24/2004, pp. 29; Spencer, 2008, pp. 196]
Radar Screens Highlight Numerous Flights - A plane’s transponder is a device that sends that aircraft’s identifying information, speed, and altitude to radar screens. [Washington Post, 9/16/2001] There are three specific codes that pilots can dial into their transponder to signal an emergency: “7500” signifies a hijacking, “7600” signifies a loss of radio, and “7700” signifies other emergencies. [Spencer, 2008, pp. 25-26] Amid the current crisis, FAA radar screens begin highlighting a growing number of flights over the oceans that are transmitting warning codes. According to author Lynn Spencer, “One foreign crew dials in the four-digit code for ‘hijack,’ just to let the authorities know they are aware of what is taking place.” [Spencer, 2008, pp. 196-197] In response to a request from the FAA, Canada will agree to open its airspace to all international flights that are diverted away from the United States, allowing those flights to land at Canadian airports (see 10:21 a.m. September 11, 2001).

The Federal Aviation Administration (FAA) tells the 9/11 Commission it has already given the Commission all the documents it asked the FAA for. John Farmer, head of the Commission team investigating what happened on the day of 9/11, finds this hard to believe, as the boxes of material the FAA has provided do not contain many tapes or transcripts of FAA communications on the day of the attacks. [Shenon, 2008, pp. 201] Later interviews of FAA staff will reveal there is a mountain of evidence the FAA is withholding from the Commission (see September 2003).
