1_T_Submariner:I think they left out some detail here....with a submarine at 100' you have about 45 psi on that hatch so unless the equalized the internal pressure of the submarine that hatch would not come open. (Ex. an 18 inch hatch has 11500 pounds of force pushing in on it) On most submarines you would use an escape trunk not "The main hatch". Just some help for you documentary.....
SeaHound:The diving set they had did not have a BCD, SPG and octo/back up reg!
DandyDon:I keep seeing this one pop up on my Subcribed Threads list - are people still taking this seriously...?? :11:
