Many small private planes have facilitates to relieve one self.

Our female counterparts are forced to wear depends, I don't envy them at all. This typically froze up in the cold, so you'd have to be pretty desperate.

This is why Chuck Yeager said it was vitally important to pee before going on a mission.

Obviously life on board a fighter jet is cramped, and there isn't a lot of room to move your body, much less use the restroom.

In addition to water, on every flight I carry an item called a pittle pack.

I typically carry water with me in my g-suit pocket, and don't worry about food unless its going to be a long flight.

Thankfully, training missions are rarely long enough that they require food in the cockpit, and it mostly just applies to deployments.Fighter pilots wear masks because the small cockpit means a decompression at altitude is much more likely (read: certain) to result in immediate loss of oxygen supply, whereas in an airliner you have a few minutes to fit a mask.FWIW, it is not just fighter pilots that have this issue.And just to add one last layer of difficultly to this impenetrable force field, I've got to dig myself out from between the folds of my boxer briefs. I've managed to free myself only to discover that the tip of my business end is only barely protruding from this labyrinth of zippers and belts (size may not matter in the bedroom, but it sure as hell matters right now).The next question you have to ask yourself is, do I have enough time to keep digging, or do I need to attempt to arc it into the bag? Third (The carrier pilot): Boom, OK three-wire trap! I drop bombs, piss in bags, and then return home to land on a boat. and I'm covered in piss because I didn't secure my pittle pack before trapping on the boat.Second: How do I get my junk out of this rocket powered chastity belt?
