So at the moment I'm taking a look at Visual Studio 2010 - basically test-driving a few features including the test suite and built-in refactoring tools. I thought a good way of doing this would be to build a simple weight & balance calculator for a Robinson 44.

Anyhow, while reading the operating handbook to get an idea of the weight & balance calculations, I came across this gem:

I can't help but wonder who might be happy operating in a fault-intolerant environment like aviation, but still need a helpful safety bulletin explaining that letting their passengers head-butt a rotor whirling at near the speed of sound might be a bad idea.

This guy perhaps?
