What the Hell is a Jesus Nut?
Ron sent me a picture of a rather important piece of hardware. On a UH-1 helicopter, the main rotor is held on by ONE part. A single nut. It's been dubbed the Jesus Nut. As I was gazing at the picture, slowly absorbing the importance of this single part, an involuntary "Jesus" escaped my lips. And thus was the obviousness of the name origin made plain to me. I guess it makes some engineering sense. If there's a part that simply can not fail, there are two ways to approach it. Make several redundant parts, or make one part and over-engineer the Hell out of it.
