The SR-71 and U-2 flew plenty high and had enough oxygen. When you’re high enough that there’s no oxygen, you have no atmosphere, and then your wings and turbines don’t do anything useful. That means it’s rocket time.
Also, depressurization happens, and the risks and complexity of workarounds increase with altitude.

That's why the pilots were literally wearing spacesuits. https://images.app.goo.gl/KjqGARoyiddhDxAE6 https://images.app.goo.gl/KjqGARoyiddhDxAE6
- Scramblejams 7y agoGP was referencing oxygen in regards to combustion, not the cockpit. The space suits weren't because of the cockpit altitude (when the cockpit was pressurized), they were because the crew were operating well above the Armstrong Limit and no amount of oxygen could keep them awake in the event of depressurization without the suit.
