The first production F-35B Lightning II short takeoff/vertical landing multirole fighter for the US Marine Corps was flown for the first time on 25 October 2011 at the Lockheed Martin facility in Fort Worth, Texas. Lockheed Martin test pilot Bill Gigliotti put the aircraft (Navy bureau number 168057) through a series of functional checks during the nearly one hour sortie. This aircraft will be delivered to the F-35 Integrated Training Center at Eglin AFB, Florida, by the end of 2011.
