I want to listen to an >hour-long podcast episode where several people wise to the relevant history argue about why none of the great sailing societies were able to adapt their knowledge and develop even (hang gliders eg) rudimentary aviation. Who would be the right people?

Fixed-wing flight is aerodynamically like tacking rotated 90 degrees right? I don’t think people actually understood the principles that made tacking work until quite late. It was discovered late and only understood practically I think. Like alchemy type mental models.

I learned to sail a few years but could never remember the jargon. Yeah, whatever range of points of sail you get an aerofoil effect as opposed to a pushing effect. Which I think would be all against the wind points up to 90 degrees
