I have several P38s and the larger B52 in both my BOBs. Be horrible if I came upon a can of ham and mofos and couldn't get into them. Or pork slices. Or the spaghetti with meat sauce. Or my personal fav, the chicken noodle soup.

The can openers were a right of passage back in basic. I maintain one on my keychain, carrying it on your dog tags only guaranteed an owie when you went prone and it was open.

But back to the main topic, aviators usually have two kits - one they wear in a vest, one someplace in the aircraft. In the USAF fighter ejection seats have one attached. The transport pilots have several onboard. Helicopter pilots have one large kit on board, location depends on the bird.

The vest kit is immediate E&E stuff and some first aid. The larger kits have the "shinies".
