What a terrifying situation, I don't think I could do for an hour what those men do everyday. I heard the men who are trapped radioed a warning to the other 9 who escaped, so at least they helped save their buddies.
I hope water is not in that chamber, I don't think anyone knows for sure that it is. It's probably another 13+ hours to go and that's a very long time to try and survive in icy cold water.
It's very frustrating hearing about this, you want to drive down there with a shovel or something, but there's nothing they can do to speed the process up that is not being done, I'm sure.
