<div dir="ltr">Entangled to me is the operative word. These little boats all have multiple means of surfacing and would not require you to flood and escape if you had a loss of power, ran out of HP air, etc. Its really only entanglement that I see as likely to cause you to bail. However, if you don't rip yourself free with MBT blown, thrusters pushing, and emergency weight dropped, then you would probably need an awfully big lift bag to make a significant difference to the situation. Or think of it another way... you already have lift bags, they are called MBTs.<div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">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.<br>
Just a thought<br>
