Air Force F-35 makes first night flight
An F-35A training pilot took off Monday at Eglin Air Force Base, Fla., for the Joint Strike Fighter’s first night training sortie. Previously, the service’s training syllabus explicitly prohibited the advanced stealthy fighter from flying at night or during adverse weather. But this delay wasn't due to a technical problem, it was due to different air worthiness standards in the various services flying the plane.
