Regulations (or lack thereof) aside, I would never crawl inside that thing if my life depended on it. I couldn't imagine shelling out stacks of cash to sit inside that tin can. I was shocked when I first saw videos. How could a potential patron look at that and go, "I'm okay with this."
I don't think they're going to locate the wreckage for a long time to come. And I think it's safe to assume that, at this point, there are no survivors.
