Just to clarify and add to what you said, equity shares are not stocks. The gov gets dividends and such, but it isn’t stock that is bought and sold on wall street. It’s all about profitability and not about speculation. If the company makes money, so does the gov. If it loses money, the gov loses money.

I frequently fly at 10 to 12 thousand feet msl and have no issues. Supplemental O2 is only required from 12500 to 14000 for durations longer than 30 minutes. It is required above 14k for the crew according to the regs. At 15k, everyone on board needs oxygen or a pressurized cabin.

Done, and link forwarded to my non Lemmy using selfhosting mentor. Maybe can get at least one more respondant. Maybe more. Good luck!
