I'm surprised by the point about pressurization... cabins do depressurize on ascent, but... marginally. Would a difference in a few thousand feet atmospheric pressure, equalized SLOWLY, really have been that big an issue?!
- phkahler 5y agoIIRC planes are pressurized to 6000' equivalent, and a quick Googling show that to be 11.7psi or about a 3 psi drop vs ground level. Also, changes of much less than that can cause discomfort in your ears if not equalized. I have no idea what 3psi does to the lungs, but with all the discussion about ventilators from 2020 I'd say that's a LOT of pressure on them.
