It doesn't look like a difficult thing to achieve these days. The USAF have landed a Global Hawk at Ramstein within the last few years...there a plenty of UAV's in use all over Afghanistan, many of which are locally controlled for take-off and landing but controlled from the States for tactical ops.
I did hear an "aircraft accident" broadcast over there when a UAV went off the side of the runway..."Zero P O B".....the ambulance turned up anyway
