It’s an old WW1 or WW2 story. They were constantly trying to improve their planes and thus analyzed the returning planes to figure out where they needed more protection. However, as the story goes, they did not account for the fact that the bullet holes where only in non-critical spots, because the planes that got hit on critical spots did not come back.

Oh wow, I wonder how many people actually watched the video? Guess the title was a little too baity for lemmy. Pobably works better on YouTube.
