Well I think you are making some very broad extrapolations from one tiny data-point. There are indeed pilots out there who are not technically minded at all but nevertheless make really good pilots. On the other hand there are plenty of technically very qualified pilots too. For example, if I can be excused the immodesty, I have a double-first from Cambridge University in Aeronautical engineering, and a Masters degree from M.I.T in aviation technology. Does that make me a better pilot? No, not at all - it just made the theory exams easier, and (hopefully) might make me more attractive to a potential employer.
