What is the landing strip/airport/base on his computer screens? All three screens seem to be different shots of the same location. Was he practicing to land at this location?

"What is the landing strip/airport/base on his computer screens?
All three screens seem to be different shots of the same location.
Was he practicing to land at this location?"

Who knows what what runway and airport that is?
The computer's history would tell us.

When you sit at the controls of that simulator, the three screens should merge together at their edges, giving you a 180 degree view of the position that the aircraft is in.

The simulator's aircraft position appears to be flying over that airport at about 500 to 1,000 feet above ground level.
But without being at the controls of that simulator, it's hard to tell what he was doing.
