In my younger years, I was very active in general aviation.
I was an airplane and instrument flight instructor (CFI-AI #1722889), and instructed in the Chicago area when I was employed with Motorola in Schaumburg in the mid 1970s. I especially enjoyed instrument instruction out of Midway airport.
My first airplane was 3933E, a 1947 Aeronca Chief with a Continental A-65 engine. It was a two-place side-by-side taildragger. I ultimately replaced the 65-hp engine with an 85-hp engine for improved rate-of-climb and cruise speed.
