Thank you, John and Adlerdriver. That is exactly the information and understanding I was looking for. You explained it in a way that is completely understandable to me. What was most interesting to me are the tradeoffs in cabin pressure and aircraft operation and maintenance.
My Dad was a retired Flying Tigers 747 Captain, and I worked for 27 years at Tigers and Fedex (in sales). I don't have any expertise in this area, obviously, but I do have a lot of interest.
I appreciate you taking the time to explain everything in layman's terms.
Thank you!
Mark
