Dark Star first flew on March 29, 1996 at Edwards Air Force Base, Calif., but it crashed during its second flight on April 22, 1996. The second Dark Star, which was modified to increase its stability, first flew on June 29, 1998. During this 44-minute flight, it successfully executed a fully automated flight from takeoff to landing using the Global Positioning System, and it reached an altitude of 5,000 feet. On Jan. 11, 1999, the second Dark Star completed its first high-altitude flight and reached an altitude of 25,000 feet on a 2-hour, 37-minute flight. Two additional Dark Star vehicles were completed, but they never flew. In late January 1999 the Department of Defense terminated the Dark Star UAV program because of budget cuts.
