This article reminds me of the movie "Stealth".

Earlier this month a joint DARPA/NASA project successfully demonstrated the first ever autonomous inflight refueling. A modified NASA F/A-18 operating as an unmannned robot plane refueled from a conventional 707-300 tanker aircraft. The tanker needed only a small piece of additional equipment to assist the UAV with relative navigation. The F/A-18 UAV had pilots aboard in case of emergency but they was not needed (the DARPA photo shows both pilots holding their hands up during the refueling). The goal is for miltary UAVs to "locate tankers, form up, accept clearances, refuel, and disengage without any human intervention". The ability to refuel will be critical if UAVs are to be used for unmanned strike operations.
