Presuppose that you are Yossarian's advocate. Rule out the solutions in the 1961 novel that appear unlawful and too dicey, such as deliberately self-inflicting wounds or a crash
and fleeing to Sweden.
Getting shot down or crashing a plane could have maimed or killed Orr, obviously! Sweden and the USA signed an extradition treaty on 14 March 1983.
How would you gainsay Yossarian's Catch-22 with solely logic, to excuse Yossarian from flying on the ground of insanity? Wikipedia logically formulated it.
Or would you need to plead some other excuse ASIDE insanity, e.g. physical illness? But this feels like a strawman fallacy, because now I'm changing the premises behind this original Catch-22!
