According to a local radio station there is a USAF F-16 "photo shoot" underway somewhere around the DC area. There have been several F-16's go over my office building, and a military-appearing helicopter was hovering south of here waiting for one to go overhead. I don't know if there was someone on the chopper taking pictures, but that's a logical guess.
I can't tell that inbound traffic into DCA has been affected (winds are out of the south today).
Anyone have any more info on this?
