If that's true, then we should be doing a serious marketing campaign
aimed at power pilots who have let their medicals lapse. That's the
really low hanging fruit.


Low hanging fruit? Perhaps not. I knew a fellow a fellow software
engineer (owned an Aztec), that was about to ditch a 6 figure software
career to fly commuters for peanuts because he "just loved to fly" (his
words). When i mentioned soaring to him, he just shook his head. It
either rings your chimes or it doesn't - and flying one thing does not
automatically translate into wanting to fly something else.

Did this guy ever take a glider ride?


Not that I know of. He showed no interest at all.
