Yes, I have the report in a diving medicine book ( would have given the title but I canot find it at the moment. There was a gradient of about 8 bars.

You would not like to read this before going to offshore diving. - Matthias Wendell Grogan schrieb: > > The story, as I got it, was that a tender opened a hatch that connected a diving > bell to the surface chamber before the two had been properly sealed together. > I've been trying to remember where I heard the story.
