The tests were intended to ensure that any attacks over the Canadian border or coastlines would be detected and subsequently stopped. The results of the tests were classified until 1997, due to fears that they could be used by the Soviet Union in order to more effectively engage the US in the event of World War III.In these exercises, all US civil air traffic was grounded (sometimes up to 12 hours). They involved 6,000 sorties flown by air forces from the US, UK and Canada, simulating Soviet fighter / bomber attacks against New York, Chicago, and Washington. This made it the largest military aviation exercise ever held.In reporting on the September 11 attacks in 2001, these exercises were often overlooked, with news agencies reporting that the similar, but unplanned, evacuation of US airspace during that incident was the first ever clearing of US airspace of all civilian aircraft."@en }
