How much did Bush have to do w/ landing all airplanes post 9/11?

Someone cited the landing of all aircraft w/in a short time after the WTC crashes as one bit of evidence that Bush is a quick and decisive leader.

My wife, who has an Emergency Management degree, doubts Bush had much if anything to do with that. She says probably the procedures were already in place and were ordered by someone much lower on the chain than the President.

Does anyone know what the truth of the matter is?

According to the Official 9/11 Committee Report,

So it appears the decision was made by FAA command people amidst all the chaos.

Slight hijack, but mad props to the controllers and pilots who managed to land every aircraft in American airspace without a single accident. Talk about a nightmare – pulling down several thousand spinning plates when the boss stops them all at the same time!
