A Defense agency has developed an on-board flight system that connects an airplane to a re-fueling aircraft without the need for a human pilot, allowing unmanned fighter jets to remain in the air longer. The technology uses exact inertial, GPS, and video measurements to latch a probe into a 32-inch basket trailed behind a tanker.
The first-ever unmanned refueling took place in August 2006, the Defense Industry Daily, reports, and the military has completed 10 additional flights since then. One successful demonstration occurred at a speed of 250 MPH, 18,000 feet above the Tehachapi Mountai. (More Navy stories.)
