"A pic of the Global Hawk UAV that returned from the war zone on Monday under its own power. (Iraq to Edwards AFB in CA) - Not transported via C5 or C17..... Notice the mission paintings on the fuselage. It's actually over 250 missions.... (and I would suppose 25 air medals). That's a long way for a remotely-piloted aircraft. Think of the technology (and the required quality of the data link to fly it remotely). Not only that but the pilot controlled it from a nice warm control panel at Edwards AFB. It has really long legs- can stay up for almost 2 days at altitudes above 60k.
They flew it via satellite control to Australia, and we flew missions during OT&E that went from Eddy to upper Alaska and back non-stop.
