The fact I was a airplane nut led me to reading about all kinds of distantly related things. For example a book on the Flying Tigers summarized the history of China. As a result when we got into 20th Century History in the 12th grade I was light-years ahead of all my fellow students; it got downright embarrassing at times. I ended up taking the exemption tests for US History in college and got credit for two courses, 6 credits, without ever drakening the door of a college history classroom.
Being an airplane nut also led me to an interest in vintage electronics. I have more WW2 stuff than I do modern day equipment.
