[PSUBS-MAILIST] emergency lift bags

[hank pronk via Personal_Submersibles]

--------------------------------------------
Hugh,
If I was entangled in a net or line  that was attached to the bottom, I think I would be happy to have an extra 5,000 lbs of lifting force.  I would prefer to have 5,800 lbs force trying to break free than 800lbs force.  In my line of work, when I can't lift it, pull it or push it, I add more power!  It might be futile with an extra 5,000lbs but I would sure like to opportunity to try.
Hank

 When talking with a friend
 about escaping from a submarine, he asked why
 can't your sub have a lift bag capable of
 raising the sub even when full of
 water.  I
 could not give a good reason why not.  A large volume of
 air would
 be needed of coarse.  Some fast
 math on a napkin revealed that 6 80cuft
 scuba tanks could raise Gamma from 600 feet. 
 Two 240cu ft tanks strapped to
 the bottom of
 a sub and two lift bags, one at each end  could do it. 
 Why
 bail out why not just raise the whole
 thing unless your tangled and stuck of
 coarse.
 Just a thought
 Hank
