> Seven men in the history of humanity stand apart from the rest of us. These are the Apollo command module pilots who spent time alone in orbit around the Moon, while their colleagues walked on the lunar surface. "Seven"? There were six Apollo missions that landed on the Moon: 11, 12, 14, 15, 16, and 17. Perhaps he gets seven by including Apollo 10, in which two astronauts did take the lunar module out and nearly land it, leaving the command-module pilot alone. But then the sentence is still incorrect; they did not walk on the Moon.
