Since the program’s start in December 2006, both past and present models of the F-35 have been flown 3,464 times.
That figure includes 91 from the original test model, 2,510 from system development and demonstration models and 863 flights for production milestones.
Testing has occurred at Edwards Air Force Base, Calif.; Naval Air Station Patuxent River, Md.; and Eglin Air Force Base, Fla.
Pilots at Eglin’s 33rd Fighter Wing and two Air Force test pilots are reviewing the jet’s conventional takeoff and landing version, with the review also evaluating how the wing carries out the test.
