OIAA has beefed up security at the airport. Heard them the other night kicking out a person because he was sleeping on a bench. Plane spotting, I am sure, is on hold for now. I read articles about this weeks ago.From WH Press Briefing a few minutes ago, POTUS arrives tomorrow afternoon and will close out the visit with a dinner at the Aviation and Space Museum Friday evening. A better schedule will be available this evening in case anyone is doing AF1 spotting.
