Drifter, you're right on! I was lucky enough to be trained as a machinist and drafsman in H.S. in the 1950's. Learned engine mechanics in the U.S. Air Force and later in life tacked on the "Academic" degrees. At an honors award meeting with the Dean I voiced the unpopular words that the mechanical skills required much more effort than the academic ones. I even become a commercial, multi engine and instrument rated pilot. In the end, I value the "mechanic" title the most.
