It appears it's not the 1st time Quantas has problems both with oxygen tanks and oxygen masks. https://en.wikipedia.org/wiki/Qantas_Flight_30 https://en.wikipedia.org/wiki/Qantas_Flight_30 "The flight was interrupted on the Hong Kong leg by an exploding oxygen tank that ruptured the fuselage just forward of the starboard wing root" "After the accident, four passengers said that their oxygen masks did not deploy, whilst others had deteriorated elastic. It was stated that these passengers were deprived of oxygen until the plane had descended to a breathable altitude."
