"Back in ancient days (before the fire burnt the water filled escape tower in '68) all submariners made qualification escapes from a 100 ft tank of water that was the tallest structure in the New London area (which was the reason the fire trucks could not stop the HP air/ hydraulics fire). Two types of escape -- a free escape with only a lifejacket, and the lifejacket plus Stenke Hood (a transparent plastic bag over the head with an air bubble - so you breathed (out obviously) into a "normal" environment instead of venting directly into water)"

Yup. I made that 'dive' back in '61 during submarine school there.
