Harrison Ford was flying a vintage model PT-22. known commercially as the Ryan Aeronautical ST3KR, when he lost engine power on Thursday and ditched on a golf course in Los Angeles, resulting in a broken arm and a gash to the head. Even crashed and crumpled, the actor’s plane had the unmistakable markings of its illustrious past — gleaming aluminum body, yellow markings on the wings to indicate a trainee, the white star in a blue circle signifying the Army Air Forces.
