I've been watching the aircraft movement and the aircraft known to us as usually being flown with the callsign AF2 (Boeing C-32A B752) spent most of the day Wednesday flying in circles over and around the Chesepeak Bay area. Thursday, it flew to to Tucson Arizona under the callsign "SAM635". Well, it just left Monterray Airport in California flying under the callsign "SAM635" again. Not sure where it's going this trip, but it is west of Phoenix Arizona heading east.
