The way the bottle was filleted open, it looked like a simple overpressure rupture. there should be a blowout disc the ruptures at a set pressure below the failure point of the bottle.  Why that didn't happen here, I don't know. I'm also thinking about using nitrous on my plane. It would certainly help getting out of short back country strips or high pressure altitude situations without having the penalties associated with having a turbo charger. It looks like the same thing could have happened with an O2 tank. Amazing amount of damage for the size of the tank. Perhaps if you were still thinking of using nitrous, you should think about keeping the tank no more than 1/2 to 3/4 full to give a safety margin.
