A few general comments.
A jet propelled oxygen tank takes a fair amount of travel distance in meters or yards to get up enough velocity to punch through aircraft skin. (reference the Mythbuster documentation on TV)
Exploding oxygen tanks leave smaller fragments behind to pepper the inside skin.
The support for the oxygen tanks is very likely to be compromised when the fuselage ruptures nearby.
Explosive decompressions create pressure gradients across nearby large area surfaces which in turn cause them to accelerate outward towards the hole.
To my knowledge no investigator is saying the oxygen containers ruptured first.
Anybody got any better schematics or pictures to corral this discussion
