Grounded Again?

When I read that the FBI plans to mobilize 5,000 agents in the U.S. as soon as the shooting starts in Iraq, I begin to wonder. When this ramp-up is compared to the days immediately following 9/11, I get suspicious.

Are the nation's airlines going to be grounded again, too? This would comport with the "threat reduction" stance that the feds are ready to adopt. At a minimum I would expect some flights in and out of Reagan National Airport to be re-routed elsewhere.

Until I hear some official denials—maybe even after I hear them—I'm assuming the worst.
