IF a scuba tank (in worst case, filled with pure O2) ruptured adjacent to a full auxiliary fuel tank,
Scuba tanks are filled with compressed air or sometimes Nitrox, which is air with a higher oxygen concentration.
Why would it rupture? Most modern tanks have a "burst disc" so when left in a hot car one day if filled too much they vent safely.
As mentioned above, divers do not usually travel tanks, pick them up locally, much easier. That is not to say it is not possible.
Why don't the co2 cylinders on every lifejacket under every seat "rupture"?
Why don't the on board pilot oxygen cylinders "rupture"?
How come the champagne bottles on board do not explode?
How come the tyres don't "rupture" on the rims?
