WASHINGTON, July 11 (Reuters) - U.S. officials agreed on Friday to lift a fleet-wide grounding order for the Lockheed Martin F-35 jet fighter after inspections of every aircraft determined that an engine fire last month was a one-time mishap and not evidence of a systematic problem.
The decision to permit the planes to resume flying will allow one British and three U.S. Marine Corps F-35s to take part in Britain's Farnborough air show beginning next week, said the officials, who spoke on condition of anonymity.
