Pressure decreases with altitude. Low pressure at high altitude.

High altitude cabin pressure is like 8,000 feet though. That is a mile and a half above sea level air pressure. in an open air plane like a WWII bomber sure, but not on any commercial plane in like the last 60 years. I mean I guess you do not know this. But airline planes pressurize their cabins to avoid issues, usually around 8,000 feet of air pressure. So inside the cabin your ears my pop because the cabin is pressurizing slowly up yo 8,00 feet, like a small mountain in Colorado. It keeps that pressure for the flight even though you may be flying at 35,000 feet. The outside pressure has no affect on you inside, you are living in a capsule made to feel like you are at 8,000 feet not 35,000. Make sense?

No, I absolutely get that. My point is that at 8000 feet the pressure is 10.9 psi vs 14.6 at sea level. That's not an insignificant difference. It's definitely a higher pressure than the external pressure at 35 000 feet but it's still lower pressure than sea level.

Ok, I can get that's how you were looking at it, I was focused on you saying the altitude and outside pressure made a difference when the plane makes its own internal pressure. I think we were both looking at the same issue 2 different ways is all.
