A paradoxical situation that has no happy ending. A popular movie with Alan Arkin in 1970, Catch-22 came from Joseph Heller's 1961 comical, yet gruesome, best-selling book about pilots in a fictitious World War II setting. The paradox was that no sane pilot would be crazy enough to want to continue flying dangerous missions. The only way a pilot would be grounded is if he were truly crazy, but if he asked to be grounded, he was then considered sane and would not be grounded.
