Except for that one hiccup, the long-anticipated demonstration went off as the 100 or so witnesses on board the aircraft carrier had hoped. "The ability to bring together the technical and operational capabilities into the carrier environment was nothing short of amazing," Winter said today. "What struck me was the ease at which everything happened," Capt. Jaime Engdahl, navy unmanned combat air system program manager, added. One of only two X-47B drones in the program, Salty Dog 502 touched down for the first time at 1:39 p.m. Wednesday, and snagged the third wire that stretched across the deck (one of many possible wires to grab) before coming to a rapid "arrested" stop.

After a "hot refueling" — in which an aircraft's tank is topped up when it's still operating, another first for the X-47B — the drone was back in the air. Drones that fly today have an element of independence, or "autonomy," a period in which the machine uses a pre-programmed set of instructions to take off, navigate and land. The X-47B was built to test the viability of maneuvering, operating and landing an autonomous craft while miles out at sea. The fact the craft doesn't have a tail makes it harder to stabilize and control.

One of the two X-47B drones (there's also a "Salty Dog 501") will be launched for more tests on the carrier on Monday, to repeat similar launch and landing maneuvers, but no new objectives are lined up.
