Doc Daneeka uses Orr as an example, when explaining the grounding of the insane and “Catch-22”. Orr is insane for not requesting to be grounded, even though he is shot down every mission he flies. If he did request to be grounded he would be considered sane for realising the risks of continuing to fly. The “Catch-22” is that you can only be grounded if you are insane. But you must request it, and by requesting it you are considered sane.
