This hamster wheel was broken in the first thread. If you had crew hypoxia due an oxygen bottle explosion in the EE bay (that also resulted in failures of all the transponding aids that the crew knows about but not the satellite phone or its satcom antenna power which aircrew did not know about), then at flight level 350 the useful consciousness of the crew would be at most 40 seconds. So all the "

You obviously haven't pulled up the inactive route made that many coherent amendments and then correctly activated the route on an FMC. Doing so while in the latter stages of hypoxia would be an impossible feat.
This was why that particular hamster wheel was abandoned.
