The flaw of averages - long read - go here https://beta.thestar.com/news/insigh...-averages.html
During the start of the jet age, the U.S. Air Force was losing a fair amount of pilots - most chalked up to pilot error. A young lieutenant realized the fatal flaw in the cockpit design of U.S. air force jets.
The US Army Air Corps, which later became the U.S. Air Force did a study on pilots and came up with "average" size and then made the cockpit fit "the average pilot"
This wasn't too much of an issue with prop driven planes, which tended to be slower and a bit more forgiving. Early jets were much faster and much less forgiving.
The long and short of this is that the lieutenant mentioned above went through 20,000 people that fit the pilot size range qualifications and did not find a person that met the calculated average.
To their credit, the U.S. military looked at this report and made adjustments so that the cockpits fitted the pilots - adjustable seats, pedals, rudders, etc. (a lot of this started to make it's way into automobiles)
Once they found out that there was no average pilot and jet powered planes had cockpits that adjusted to fit the pilots, the rate of "pilot error" jet crashes plummeted.
I bet there are some take aways here../
