I was Airborne and had that problem, and being strapped with parachutes and back packs didn’t help, the flights became misery for me and I could not wait for the door to open and the jumping to begin.
Civilian flying was much, much worse, being locked in like that, I haven’t even tried since all these new rules started, I used to carry a bottle of booze on board with me but I understand you can’t do that anymore.
Seriously, flying bothered you but jumping out didn’t??? Do you think it was a physical thing with altitude?
