Question Mark ("?") was a modified Atlantic-Fokker C-2A airplane flown by aviators of the United States Army Air Corps to experiment with aerial refueling. It was used to establish new world records in aviation for sustained flight (heavier-than-air), refueled flight, sustained flight (lighter-than-air), and distance. The records were established between January 1 and January 7, 1929, in a non-stop flight of more than 150 hours near Los Angeles, California.
