Just watch out for oxygen toxicity. Civilian technical divers play with all kinds of NITROX and TRIMIX combinations. I won't try to speak for military divers.

In order to prevent the same thing from happening for going up very high to jump (as the pressure again drops), jumpers breath nearly pure O2 to flush as much nitrogen out of their systems as possible, so that you can just fly up very high and not get the bends...?

As for these mountain jumpers, I am guessing they then climbed down the mountain...?
