The plane was aloft for 5hours. I've got a lot of time in planes that size and things start getting painful after 3-4 hours. Definitely not a sightseeing ride, especially at about 6,000' altitude.
I just adjusted my tin foil hat and will keep an eye on the papers for a few days.
This is what "they" say is going on......doesn't make me feel any better about the situation.

A friend has flown for an aerial mapping/survey company and talks about the precision with which he as to fly. Looking at the flight paths these FBI guys aren't very good.
