David,
Andrews is NOT an air defense base, it is not a NORAD base, it has no dedicated fighter squadrons. There were 4, Four, armed alert fighters, and 4 pilots, ready to respond to air defense situations in the entire northeast US that morning. Bringing additional armed aircraft on line takes some time, not just minutes.

Why do you keep bringing up this totally IGNORANT NORAD standdown claim, made by completely unknowledgable sources? ....and you just lap it all up like mother's milk.

Uh, and the NYPD doesn't call NORAD to scramble fighters.
