HORSESHIT*!*. I worked in aerospace over twenty years and met way more than just a few very smart black guys, scientists and engineers, as well as line workers. Differences between groups is mostly noticable between the neighborhoods where people come from more than anything else, in my opinion. Neighborhoods are different, not people. I aso knew several folks, black, white and yellow, with more limited abilities, as is the case anywhere, when large numbers of people work together. And all of those folks, no matter what race anyone came from, were just as likeable, loveable and interesting to know, as anyone else, no matter what their intelligence level was or wasn't. Jack knew a hell of lot about physics, and Joe knew a hell of a lot about cooking. I learned from and enjoyed knowing both of them.
