A friend of mine is an engineer at Lockheed, and used to work for NASA some 17 years long. He explained to me the whole thing was more of a photo-op and ability to over-engineer to show who's got the bigger balls, than actually to quickly rescue people.
He basically told me one of many training astronauts have is in a long dark corridor that is submerged underwater of course to simulate low gravity. However the whole thing inside is wrapped in a plastic bag, for lack of better explanation. Just imagine huge condom big enough to fit people in it. When the shit goes down, you push emergency button and whole thing fills in with air in less than 90 seconds. Since its inside cave/corridor, air has no way to push the condom outside/up, so whole water is flushed out quickly.
He told me all they had to do is put a thick foil underwater, glue 2 sides together, making long sealed condom, and then pump the air in, making a way for kids to crawl through, with no need to dive or know how to swim, almost like they have those tubes on children's playgrounds. That's all.
