The Problem – Good Pilots Crashing Good Planes

One bleak day in the late 1940s, 17 pilots crashed for no apparent reason. At this time in history, the United States was experiencing a baffling mystery: good pilots were crashing good planes on a regular basis and they didn’t know why.

At first, the pilots were blamed. The planes were tested repeatedly but no defects were found. But the pilots knew it wasn’t them.

So engineers had to think harder. Were pilots bigger than they had been in 1926? Was that messing with how cockpits were designed?

The Law of Averages – Not A Single Average Pilot

To find out, a new study was launched to take the measurements of over 4,000 pilots. They measured down to the details, including thumb length, crotch height, and even the distance from ear to eye. Then, they calculated the average. Everyone believed that this would result in a better pilot-to-cockpit fit and that, finally, there would be fewer crashes.

But Lt. Gilbert S. Daniels had doubts. He chose to look at each of the 4,000 pilots’ measurements side by side with the average and found a revelation that was shocking for the times. Not a single pilot even came close the measurements of the average.

Designing a cockpit for the average pilot meant that it was essentially designed for no one.

This was an enormous breakthrough. But how would they be able to fit each cockpit to an individual pilot? That was not possible.

Enter adjustable seats. While pilots still needed to be within a certain range of dimensions, these new adjustments revolutionized production. The solution was cheap, easy, and better yet, pilot performances soared.

Below is the TED talk to prove it.

This is crazy to think about because they are taking measurements of a select group of people whom you would assume to be "average" because the Air Force only accepts certain weights/sizes.

This story was told to us as an allegory for education and I loved it. They made a seat to fit every “average” dimension of an adult male, only to find that not one single pilot fit the average in every dimension. The connection to teaching was that we can teach an “average” lesson to “average” students, but every kid is going to have at least one area where they are unique and need something different, so it’s better to build that flexibility into your lesson in the first place.

If anyone was actually average, they'd be incredibly remarkable.
