I did such a calculation days ago, but I did it for a five hour flight.
What about the likelihood of those freezing in Texas. Best I can tell, 5 in Texas died from hyperthermia during the recent storm, and one of those died while outside. I'd be shocked if Texas averages more than 0.25 such deaths per year due to power outages. I believe there are 28,000,000 people in Texas. Once again, do we spend billions and billions of dollars to save one person every 4 years? Sorry, but anyone saying yes is a dummy.
My airliner example was simply another example of potential spending money to make things "safer". Should we can spend every penny that we have to make things "safer", and don't forget, every plane holds a granny. BTW, I don't really believe that we should spend unlimited money on jet planes to make them a tiny bit "safer". After all, if we are really all about safty, let's put a speed limit of 20 mph on the interstate highways and a 10 mph limit on surface roads. Just think how many grannies we could save!
