“Yeah. So I was a mechanical engineer interested in robotics, automatic control systems. And I hired into this great group at Boeing that was the ah responsible for R&D, for all the automatic control systems on Boeing commercial airplanes. And when I was there, one of the problems that my group was responsible for was anti-lock brakes, and airplanes would sometimes go off the end of an icy runway. And we knew the anti-lock braking system was giving up potential braking. It was 92% efficient.”
