Ask him what to do when entangled with a net or line attached to the bottom!

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
