I know boeing builds good planes. And builds them well. And I know the 737 has been flying since the middle 60's...first flight of type.
I flew the 737 and as many of you know, it pre presurizes slightly on the ground and fully depresurizes on landing.
I wonder if the plane might last a bit longer if it would simply wait till airborne to pressurize and completely depresurize at 200 feet agl or similiar altitude.
just a thought...just a pilot, not an engineer.
