If it's in a maneuvering state. It's still more possible than it being low over water, yet they give you a life jacket. More opportunities to put on a parachute and survive than a lifejacket and survive. The real reason they do it is to cut costs. A casing although it may burn. It will not cause disfigurement. Although I did have one land on my leg and burn the fuck out of it. The specific variants of the Barretta M9 had manufacturing faults when it came to the slide coming off. It's still pretty rare. People should study their firearms before using them and take the appropriate PPE for that firearm. The majority of firearms are robust and reliable. I think specs and ear defenders should be the shooter's choice on whether they want to go deaf over time from excessive sound exposure, or have protection from an accident that is considerably rare. I know that I can't shoot wearing safety specs. Maybe just me or not enough training, but I was trained without and don't see the need. I will say, it would of been handy the first time shooting a semi automatic when I put my eye too close to the rear sight lol
