Wallpaper Description:

In the "risk reduction flight test,", a Global Hawk UAV from NASA played the role of the aerial tanker , and Northrop Grumman's Proteus test aircraft a manned UAV surrogate, was the one in search of the refuelling boom.

Among the matters being evaluated were wake turbulence between the two aircraft, which at their closest were just 45 feet apart, along with engine performance and flight control responsiveness in the stratosphere.
