A pilot is safe after an emergency egress June 23 from an F-35A that caught fire while preparing for takeoff at Eglin Air Force Base, Fla.

The pilot was preparing to conduct a training mission at the time a fire was detected in the aft end of the single-engine, stealthy fighter. Eglin houses the F-35 schoolhouse for pilots and maintainers.

There has been no limited or fleetwide standdown as a result of the fire, according to program spokesman Joe Dellavedova.

Emergency responders used foam to extinguish the fire, and no cause has been provided. The incident is under investigation.

Meanwhile, program officials are preparing for the aircraft’s international debut. The first window for arrival of four short-takeoff and vertical-landing F-35Bs is next week. The aircraft will fly at the Royal International Air Tattoo and Farnborough air shows next month near London.

Though the B will be at the show, 11 allies have shown strong interest in buying the A model designed for conventional takeoff and landing.
