Funny story, my grandfather was an engineering grad who joined the RCAF during WW2. He survived the war, and soon afterwards - I presume during the Gemini recruitment drive - heard that NASA was looking for people with, basically, his CV - technical/engineering background with piloting skills. So, he applied, but was rejected. The reason? He was an alien, and NASA could not hire aliens. Seriously.
