N91S (Argus aircraft) back in Vegas again (8/14/2012)

N91S is now snooping, er make that flying loops around Dallas. Rather high up for observation (20kft), well unless you have some wide area video sensor.

Just a FYI, a plane spotter has caught this plane talking to Cario (Egypt) air traffic control.

The tracking of this plane is interesting. It isn't blocked, but the tracking seems to go away when it gets to interesting places. The last tracking of Flightaware had it going to Faial Island in the Azores on 2/12/2014.
