F-35A Lightning II
AF 1, one of two F-35A Lightning II joint strike fighters flying nonstop to Edwards Air Force Base, Calif., departed its final-assembly site in Fort Worth, Texas, May 17, 2010. As part of the F-35 flight test operations expansion, the jets will undergo ground- and flight-test activities for propulsion, aerial refueling, logistical support, weapons integration and flight-envelope expansion. The arrival is the first in a series that will increase the Edwards AFB F-35 test fleet to at least eight aircraft. (Courtesy photo/Angel DelCueto)
