If there is no oxygen at 35,000 feet, how do the engines work? The jets I fly are certified to 45,000 feet, and I fly there routinely.

I didn’t say there was no oxygen at 35,000 feet. I said basically there is no oxygen in reference to human survivability and normal fires as referenced in the post I was responding to.
People and jet engines can function if you compress the air.
