    Yeah, that caught my eye also. Doesn't say there aren't consequences, just says it is possible.

    Submarines are kept as close to one atm as possible, if you can handle the quick equalization in the escape trunk and exhale all the way up...

    The only time it was done by U S Navy submariners in combat, of the 13 men who escaped the USS Tang in 180' of water, 13 men escaped, only eight reached the surface, and of these only five were able to swim until rescued. Of 9 men on the bridge who did not sink with the boat, only 3 made it until morning, in all 74 of the crew perished. I believe the record for an escape in WW2 was 170' by a British submariner.

    A shipmate saw the escape test by Dr Bond and Chief Tuckfield from the Archerfish at 300'. I believe the deepest escape test was 600' later by the Brits but @Akimbo can correct me if necessary.

    I never worried about it much because most of the ocean is deeper than the crush depth of a submarine. Submariners are trained for escape in 50' of water now, 100' back in the day. The concept is simple but the execution and survival is more dificult as one goes deeper, however it is the last option, like a CSEA, before using that option it's fixing the problem and getting the boat to the surface.
