>> decompression ... happened, immediately killing everyone on board...
Well, it doesn’t “immediately kill”. TUC - time of useful consciousness is altitude dependent. At 35,000 feet, you can go from 30 to 60 seconds before you enter la-la land. A rapid decompression (i.e. a BIG hole in the fuselage) can cut that time in half. But still plenty of time to get over the “WTF was that?” and put on the mask.
FAA regulations require one pilot to wear the O2 mask above FL350 (35,000’). This is routinely ignored by aircrews.

Right idea, wrong terms. The big hole would lead to an explosive decompression, not a rapid decompression.
