In the two years before the Sept. 11 attacks, the North American Aerospace Defense Command conducted exercises simulating what the White House says was unimaginable at the time: hijacked airliners used as weapons to crash into targets and cause mass casualties.
In a third scenario, the target was the Pentagon - but that drill was not run after Defense officials said it was unrealistic, NORAD and Defense officials say.
NORAD, in a written statement, confirmed that such hijacking exercises occurred. It said the scenarios outlined were regional drills, not regularly scheduled continent-wide exercises.
"Numerous types of civilian and military aircraft were used as mock hijacked aircraft," the statement said. "These exercises tested track detection and identification; scramble and interception; hijack procedures; internal and external agency coordination and operational security and communications security procedures." <snip>
NORAD officials have acknowledged that "scriptwriters" for the drills included the idea of hijacked (planes from airports in Utah and Washington state) aircraft being used as weapons.
