There was a guy I was in NROTC with......went to A-pool, got stuck during the Hurricane Ivan fallout as a stash ENS with the Blues while no Navy students were classing up at all. Apparently the Marines needed dudes, and could offer to get them into API immediately. I don't know the details specifically, but he ended up very soon thereafter as a 2nd Lt of Marines, went through flight school, finished the Hornet RAG, TBS, and then to the fleet. Is now a TOPGUN/N7 instructor. Strange route, but I guess proof that given the right circumstances, this could happen.
