Not being a diver.... not understanding things.... the 'rescue' is confusing to me. Sure, I understand it is dangerous... but I don't see why it should be THAT dangerous. And NO, not saying I'm right.. just saying 'I don't get it'. Seems to they could have a seal both in front and behind every single kid making sure they can handle things in case of panic.. which is a real danger.

And I don't understand why they can't have an oxygen line running the entire length of the exit at the ready. With access to oxygen in the line every few feet.
