WELL, THIS IS THE 21ST CENTURY, YOU KNOW (CONT’D): The Unmanned X-47B Just Pulled Off a Mid-Air 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. Air-to-air refueling, as Popular Mechanics found during a B-2 flight, takes a lot of hands to go right. The ability of a drone to adapt to the precision flying required for refueling aircraft, and to coordinate with the humans inside the refueling tanker, is impressive.”

By “hover” I think they really mean “loiter,” unless the X-47B has more capabilities than I know.
