10:00 a.m. September 11, 2001: NEADS Notified of Suspected Hijacked Aircraft out of Canada

NORAD’s Northeast Air Defense Sector (NEADS) receives a call from a NORAD unit in Canada, reporting another suspected hijacked aircraft that is heading south from Canada, across the border toward Washington, DC. [Vanity Fair, 8/1/2006]
Aircraft Reported on Chat System – A member of staff at NEADS relays to their colleagues that the aircraft is from an “unknown departure airport, heading towards Washington,” but they do not “know any codes or anything” else about it. [North American Aerospace Defense Command, 9/11/2001] Another member of staff at NEADS calls the Canadian unit for more information. A Lance Corporal Nicholson there says only that he has seen “something on the chat” about a “possible” aircraft. [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] (Nicholson is presumably referring to NORAD’s computer chat system. [Spencer, 2008, pp. 139] )
Fighter Unit Contacted – According to author Lynn Spencer, NEADS battle commander Colonel Robert Marr contacts a military unit in Syracuse, New York, to get fighter jets sent after the suspicious flight. [Spencer, 2008, pp. 223] However, the first jets to launch from Syracuse will not take off until 10:42 a.m. (see 10:42 a.m. September 11, 2001). [Post-Standard (Syracuse), 9/12/2001]
Report Is a False Alarm – The suspected hijacking is soon revealed to be a false alarm. Nicholson will call from Canada and tell NEADS: “Be advised… that our [intelligence team] is not assessing that there is an actual aircraft problem. It’s just that there could be problems from our area.… There’s no actual aircraft that we suspect as being a danger.” He will add that his intelligence people “haven’t got any particular aircraft in mind.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]
Numerous Erroneous Reports – This is one of the numerous mistaken reports of hijackings received during the course of the morning (see (9:09 a.m. and After) September 11, 2001). According to Vanity Fair: “In the barrage of information and misinformation, it becomes increasingly difficult for the controllers [at NEADS] to keep count of how many suspected hijackings are pending. So far, it is known that three have hit buildings, but given the uncertainty about the fates of American 11 and American 77—no one knows yet that this is the plane that hit the Pentagon—the sense at NEADS is that there are possibly three hijacked jets still out there, and who knows how many more yet to be reported.” At the time NEADS is informed of the suspicious aircraft coming in from Canada, “no one on the military side is aware that United 93 has been hijacked.” [Vanity Fair, 8/1/2006]
