Like electric airplanes, someone once called Bill Lear a “Pioneer”. His retort–“A Pioneer is a Farmer with an arrow in his ass!”
Lear did pioneer a lot of projects, from radio to autopilots to 8 track tape players to Learjets. He made a lot of money–only to lose much of it with failed products. All had problems along the way–and required years of sacrifice, change, and at the cost of lives to ameliorate.
