This reminds me of a story that I think was about Yeager, where due to some human error on the part of a mechanic (I think in regards to fueling his plane) Yeager almost died, and after the accident he surprised everyone by asking for the same mechanic to be assigned to service his plane on his next flight. He explained his choice by saying expected that mechanic would not make the same mistake twice.

I probably butchered that story a bit.. anyone recognize it and have a link to the original?
