There's a recurring idea in the conspiracy whacko world that we actually
*did* "stand down" our interceptor planes on 9/11/2001. Apparently,
some folks had this weird idea that we normally ran *lots* of
interceptor flights all over the US, for, well, some reason or another,
and that we *didn't* do so on 9/11 to make sure no trigger-happy pilots
accidentally shot down those four airliners.
