Standing ready for flight
A U.S. Marine Corps plane captain, known as a crew chief in the Air Force, marshals out an F-35B Lightning II short takeoff and vertical landing variant of the aircraft May 22, 2013, at Eglin Air Force Base. The maintainer orchestrated a "hot pit" ground refueling, running the engine while receiving fuel, allowing it to take off immediately afterward for another training sortie. Assigned to the Marine Fighter Attack Training Squadron-501, the plane captain helped train up 24 U.S. and United Kingdom pilots flying the B variant to date by having aircraft ready for the daily flight operations.
