I found this story interesting:

After supporting the global war on terror for three years, Global Hawk Unmanned Aerial Vehicle No. 3 (UAV-3) received its official homecoming Feb. 20 when its wheels touched down at 11:30 a.m. Pacific Time at Edwards Air Force Base, Calif.

During its overseas deployment, UAV-3 logged more than 4,800 flight hours supporting Operation Iraqi Freedom, Operation Enduring Freedom and the Combined Task Force --Horn of Africa.

What is amazing is that this was just a prototype that was forced into service by the war in Iraq. Looks like the prototype works pretty well. Time for a few more of these babies.
