I went over to Ellington Field today to shoot some photos of the KC-135 on a stick. While there I wandered over to the flight line and found this. There were several busses and a U.S. Marshall van parked in front of an unmarked 737. I could see several armed guards and some people being frisked behind the vehicles. I checked out the registration of the 737 and found it belonged to a Wilmington Trust Company as a trustee for something. Interesting.
