United States government operations and exercises on September 11, 2001 : ウィキペディア英語版 | United States government operations and exercises on September 11, 2001 On September 11, 2001, the North American Aerospace Defense Command (NORAD) was involved in an ongoing operation which involved deploying fighter aircraft to northwestern North America. The US Military and NORAD had also planned to conduct several military exercises and a drill was being held by the National Reconnaissance Office, a Department of Defense agency. The operations, exercises and drills were all canceled following the September 11 attacks. ==Ongoing military operations== ''Operation Northern Vigilance'', was a NORAD operation which involved deploying fighter aircraft to locations in Alaska and Northern Canada.〔(【引用サイトリンク】publisher=NORAD Newsroom )〕 The operation was a response to a Russian exercise, in which long-range bombers were dispatched to Russia's high north. The operation was one part simulation, one part real world. It was immediately called off after NORAD received word from NEADS that the Federal Aviation Administration had evidence of a hijacking. All simulated information (so called "injects") were purged from computer screens at NORAD headquarters in Colorado. On receiving news of the attacks, the Russians promptly canceled their exercise as well.
