We can talk about  planning the dive to this depth, I will even tell what I 
did and why. But I have come up with the first mixes used to dive the 
"Ostfrisland", if they are wrong I'm sure the many lurkers on this list 
that were there ,but are fearful of touching the keyboard to post will tell 
me in private.
The divers (3 names are unimportant) used a Heliox travel mix 16 , a heliox 
bottom mix 12 , and then back to heliox 16 as the start of deco mix, then 
nitrox 36 , I am not sure what next but I think 02.
I have been told that one diver after changing to his nitrox deco mix 
nearly pass out. After several minutes his head began to clear and the 
danger past.Think about it, a perfectly clear head being introduced to 
nitrogen all at once at !
