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:
“General education is the best preventive of the evils now most dreaded. In the civilized countries of the world, the question is how to distribute most generally and equally the property of the world. As a rule, where education is most general the distribution of property is most general.... As knowledge spreads, wealth spreads. To diffuse knowledge is to diffuse wealth. To give all an equal chance to acquire knowledge is the best and surest way to give all an equal chance to acquire property.”
—Rutherford Birchard Hayes (1822–1893)
“If it is the mark of the artist to love art before everything, to renounce everything for its sake, to think all the sweet human things of life well lost if only he may attain something, do some good, great work—then I was never an artist.”
—Ellen Terry (1847–1928)
