A US Air Force bombardier in World War II – the incomparable and artful dodger Yossarian – is furious because of increased missions. If he attempts to avoid assignments, he’ll be in violation of Catch-22:
A concern for one’s own safety in the face of real and immediate danger is rational;
real and immediate danger is rational;
it’s insane to willingly continue flying dangerous combat missions,
but a request to be removed from duty is evidence of sanity and therefore ineligible to be relieved from duty.
