My favorite was a statistician in the late 40's early 50's who was tasked by the air force to find the 'average pilot'. The reason was new fangled jet fighters were crashing due to pilot error. At higher rates than could be anything but problems with the man machine interface.
He and his helpers took 10's of thousands of measurements of thousands of air force pilots and determined that, there is no such thing as the 'average pilot'.
Well there was. About two dozen of them. Turns out that all the measurements were uncorrelated in the already highly selected group that is air force pilots.
Aerospace manufacturers were forced to redesign cockpits with adjustable seats and controls. And the rate of accidents declined.

What's really whack when you consider it is the same neuromuscular system that allows us to walk can also be repurposed to drive a car, fly a plane and operate other machinery.
