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:
“The same indignation that is said to have cleared the temple once will clear it again. The question is not about the weapon, but the spirit in which you use it. No man has appeared in America, as yet, who loved his fellow-man so well, and treated him so tenderly. He lived for him. He took up his life and he laid it down for him.”
—Henry David Thoreau (1817–1862)
“Fences, unlike punishments, clearly mark out the perimeters of any specified territory. Young children learn where it is permissible to play, because their backyard fence plainly outlines the safe area. They learn about the invisible fence that surrounds the stove, and that Grandma has an invisible barrier around her cabinet of antique teacups.”
—Jeanne Elium (20th century)
