The trip was very planned out
Hi Dukhalion,
Yes, how he would get the suit on was not fully explained, but because they spent seven years planning the whole trip, I imagine that they worked out some way for him to put on the suit.
For the same reason, the condensation was not a surprise to him. He was merely describing it for reporters. He has previously tested the submersible on shallower dives. As to why he didn't do more in terms of the submersible's temperature control, he did not explain.
