Lad culture is a disease that should have been wiped out 30 (more than, but 30 at the least) years ago. Have fun, get drunk, be young (at heart) and carefree... BUT if that involves harassing others, exposing yourself, being a general nuisance, GFY.
Yeah, I've witnessed all kinds of erratic behaviour from the other vets. I would argue that vets are less likely to share their trauma with you, but some of them are dicks and some no longer have good impulse control (which doesn't excuse their actions).
I think the pilot was justly dealt with. But lets not pretend not talking is the only negative behaviour mentally unwell people engage in.
