# OK for a KO by Air Force technicians

Army Air Forces maintenance poster in red-brown crayon style: a ground technician with a tool case raises an arm toward aircraft overhead while a second crewman crouches near a downed plane. The headline credits 'Air Force technicians' with the 'OK' for flight. The technique is faint; the sheet shows ordinary ground crew as the people who keep planes flying.
