Question Mark (aircraft)
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.

Famous quotes containing the words question and/or mark:
“Why does man freeze to death trying to reach the North Pole? Why does man drive himself to suffer the steam and heat of the Amazon? Why does he stagger his mind with the mathematics of the sky? Once the question mark has arisen in the human brain the answer must be found, if it takes a hundred years. A thousand years.”
—Walter Reisch (1903–1963)
“The sabbath was made for humankind, and not humankind for the sabbath...”
