The Unmanned X-47B Just Pulled Off a Mid-Air Refueling

The Unmanned X-47B Just Pulled Off a Mid-Air Refueling:
"Another first for naval aviation, courtesy of the X-47B: An unmanned aircraft has executed a mid-flight refueling.
The Navy's X-47B demonstrator aircraft flew over Chesapeake Bay on April 22 and connected with a refueling tanker during flight.
This capability greatly extends the range of an unmanned aircraft and further increases its ability to hover over a target area."
