When I was in A&P school last year, we had representatives from Northrop Grumman come in and do a presentation for the class about the future of UAV's and Aviation. I remember one of the Rep's bringing this aircraft up in discussion. The X-47B is fully autonomous, meaning no direct pilot input like the predator drones, the only time a operator is in direct control is when the A/C is on the ground taxiing. The mission profile is loaded to the A/C before flight and can be modified mid-flight by an operator at a mission station, but cannot be flown by direct control remotely.
