zero traffic conflicts.

You don't need to clear the airspace. You just need to keep other aircraft
out of the way.

They do that now, only for the President, a 30 NM radius.

What is done for the President is intended as a show of power; it has no
security justification.

DFW had lots of traffic, I'm pretty sure the AA flight got
the quickest landing possible.

How many aircraft were in the air, and where were they?
