I've long had an interest in aviation history, which at times can be obsessive. For instance, I can get into such details as specific colors used to paint parts of an aircraft or specific models of electronic equipment carried by an aircraft at a specific time. It's been a blessing and a curse. It's helped me as a scale modeler of aircraft, helping fellow modelers with info on their subjects. It certainly helped when I edited books on military aircraft (and other military equipment). Otherwise, it's put quite a crimp in my social life. Hardly anyone else I know has this sort of interest in the subject. I've been working on broadening my horizons in recent years. Time will tell how well that will work in my favor.
