There were 2 people that were worried, someone's wife, and someone's mum.
I'm not in a position to say why or how that happened, however I'm sure The Kwan will be along shortly to explain that one.
As for my ego overcoming common sense. I'll readily agree that I have an ego, and sometimes it gets me into situations that are well outside my comfort zone, but this is not one of them. That ego took a back seat the moment that I was responsible for the safety of other people. Getting people through safely was the primary concern. If I'd have thought that that wasn't achievable, then I really would have called it off.
Matt, the guy that I'd trusted as a second has pulled me before, and stopped me going further than he thought I could do. He was right then, and as I've said in other places, I've always been of the opinion that if I can't explain what I'm doing, then I shouldn't be doing it.
Everyone that came to me prior to the trip with concerns had my plans explained to them, and they went away having had their concerns addressed.
I'd happily have done the same for anyone, if only so I could make sure that what I was planning was doable. If they had come up with something that I hadn't thought of, I would have factored that in, changed my plans, or called it off.
As for the inconvenience to the cave rescue organisation, apart from the underestimation of the trip duration, that stems from a decision I made at the exit to the boat. People were saying that we should send some people ahead to race out and extend the exit expectation. As I was responsible for everyone, I was of the opinion that my decisions should be based on their safety, and nothing else. It was paramount to me that they all make it out without injury, and everything else was secondary to that. So i decided to stay as one group, not only because I wasn't 100% sure that anyone sent ahead wouldn't get lost, but because I didn't know that I wouldn't need those people further on into the trip.
While the CRO call out is regrettable, I knew that it was going to happen once it hit midnight, but the choice as I saw it was either having a call out for a late arrival, or having a call out for a serious injury from people rushing and cutting corners.
I still don't know if I made the right decision on that one, but as everyone made it out alive and without injury, I'm happy enough that it was the best of two bad choices.
