Global Hawk Passes Wet Runway Test: The Global Hawk unmanned aerial vehicle test team at Edwards AFB, Calif., has completed testing the UAV’s braking capability on a wet runway. Officials say it was the first-ever such test with a UAV. The testing has proved that the vehicle’s anti-skid braking works and will provide data in making decisions about whether a Global Hawk can safely land.
