Also the fact that the turbulence models for design stressors, for planes manufactured today, were from those original measurements in the 60's. Science needs to stay at the forefront here with the earth changing, I only hope that the political situation improves to allow that to remain a priority.
I love flying for the engineering aspect, when I manage to turn off my scared animal-brain. It's absolutely mind blowing the technology and iterative designs these machines have gone through.
