The first F-35B Lightning II stealth fighter passes overhead at 40 knots (46 mph) prior to a slow landing at Naval Air Station Patuxent River, Md., on Wednesday, March 10. The flight was one of the last missions before the aircraft's first vertical landing, and confirmed the jet's power and controllability at very low speeds, according to Lockheed Martin. The aircraft's short takeoff/vertical landing (STOVL) propulsion system generates more than 41,000 pounds of vertical thrust, and enables airspeeds from zero to Mach 1.6. It will be capable of operating from small ships and austere bases near front-line combat zones. F-35 Lead STOVL Pilot Graham Tomlinson was at the controls for Wednesday's flight.
