Fox is reporting there's been an "incursion of airspace." Eyewitnesses say there's lots of running and screaming, which seems appropriate. At Wonkette HQ, we're hearing jets flyover.
UPDATE: CNN reports: Fighter jets circled a small, one-engine plane and fired two "warning flares." (They apparently got Bernie Shaw out of retirement to report this.)
Evacuation over, everyone's headed back in.
Also: The President was on a bike ride.
