Diving into the Unknown Trailer

There is an amazing graphic representation of the cave itself, as well as the accidents and the recovery process. See http://www.vg.no/spesial/2014/dodsdykket/index_eng.php .

Because this is what you see in a vid sequence?

Yes. They said it's actual footage of the deep section... not in this video but in the presentation that was posted at the time.

The presentation seemed pretty detailed but I don't remember any mention of setup dives... so they could not have had any safety tanks on the Stein-something side of the cave.

What's BO? You mean BOB? I don't know, I didn't see one on the diver in the video.

I found more info on the recovery, I didn't see much on the initial dive and I haven't seen an accident analysis either.

Edit: Thanks vinegarbiscuit, that's the presentation I was talking about.

This seems to be an even more detailed account of the plan, the accident, and the recovery efforts: dynamic.hs.fi/2014/deep/

BO = Bail Out
I remember reading something about placing gear on the other side some time earlier (different trip)..
Nevertheless, I think that judging the Bailout from a video sequence can't be done and it tells us nothing as it would be pure speculation..

I was ASKING, I wasn't judging anything.

Apparently they had an BOB. From vinegarbiscuit link: ''...agreed with Huotarinen that he would practice switching to the the bailout rebreather in the deep. The switch was a success, and he used his reserve system for a few minutes.''

The big problem with a BOB in that cave is, the low temperature might prevent the scrubber from starting to remove CO2.

This myth has already been scientifically and anecdotally proven wrong. Prebreathing a scrubber to warm it up is not necessary for it to begin working. It will remove CO2 even when cold, just not as effectively until your exhaled gas warms it up a bit. IIRC paul even tested this on his ANSE machine.

Just watched that and it was really quite good. And informative.

I'm amazed that with that much deco blown by the three survivors that there weren't more complications from DCS. It's not like they hopped out of the water and hit the chamber in the next bound. And two of them had to climb out of the cave and walk back down the mountain to get to the farmhouse.

Just goes to prove that as predictable as we try to make things, as much risk as we try to mitigate, at some point it's just damn luck that keeps up alive or leads us to shuffle off this mortal coil.
