They all heat the pools these days. Apparently In days of yore when us more mature aviators were doing the dunker someone realised that we weren't learning anything because we were fretting about lack of feeling in our nethers.
Then the health and safety gestapo weighed in about it being bad for our health. Personally I'd like to see a few of them floating in the North Sea on a dark and frosty night
