These trailers are where Air Force personnel in full flight suits fly Predator missions in AFG. Two controllers, one "pilot", and one "sensor", fly and operate the unit and weapons systems thousands of miles away.
Are you sure? I'm pretty sure that Creech is where drones are controlled from. Also, I point out that just because the pilot is not in the aircraft does not mean that it doesn't take just as much skill to fly, so I think "quotes" around the word "pilot" in your description is not correct.
Absolutely 100% guarantee. And pilot is in quotes because that's what one of the two jobs is formally titled. Pilot, and Sensor. One programs and executes the flight plan, and one performs wizzo functions- e.g. runs checklists, and master arms weapons. Trust me.
