The view from a KC-135 tanker from Altus Air Force Base, Okla., while the United States Air Force Test Pilot School’s VISTA (Variable stability In-flight Simulator Test Aircraft) F-16 connects to the boom during a flight test March 17, 2011. The maneuver is part of the Basic Envelope Air Refueling Control Laws, or BEAR CLAW, test project, which is aimed at obtaining preliminary data leading ultimately to have a remotely piloted aircraft conduct air-to-air refueling.
