As turchin said, it’s possible that the person in the plane accident exists in both a “real world” and a simulation, and will survive in the latter. Or they quantum tunnel to ground level before the plane crashes (as far as I know, this has an incredibly small but non-zero probability of occurring, although I’m not a physicist either). Or they’re resurrected by somebody, perhaps trillions of years after the crash. And so forth.
In fact so called QI does not depends of QM at all. All it needs is big world in Tegmark style.
This means that many earths exist in the universe and they are different, but me is the same on them. On one earth the planes kill everybody and on the other there will be survivors.
