Another one of Yuri Gagarin's reported comments after his space flight:
Anecdote in New Age Journal, Vol. 7 (1990), p. 176:
When Yuri Gagarin, the first man who went into space, returned to Earth, there was a huge reception in his honor. As his close friend and cosmonaut colleague Alexei Leonov tells it, then premier Nikita Khrushchev cornered Gagarin. "So tell me, Yuri," he asked, "did you see God up there?" After a moment's pause, Gagarin answered "Yes sir, I did." Khrushchev frowned. "Don't tell any one," he said.
A few minutes later the head of the Russian Orthodox Church took Gagarin aside. "So tell me, my child," he asked Gagarin, "did you see God up there?'" Gagarin hesitated and replied "No sir, I did not." "Don't tell anyone."
Of course, if he'd really expected to see the Almighty Cod, perhaps he should have been in a submarine instead of a spaceship...
