No oxygen problems that I recall. I don’t think there’s a hypoxia risk until 10K feet? Cold I’m sure because it was like flying with a window open. The heaters for the cabin air probably couldn’t keep up.
Hypoxia risk is usually around 14k feet. 7k feet is like skiing town tree line altitude, cold as fuck but not dangerous. Fascinating story, thanks for sharing.
