As I said, I lean toward the angle-of-attack arguments now. Take
a flat rectangle, tilt it into the wind. The wind blows against the
front which is also the bottom, not the back/top. So the
forces are on the bottom.

The day the physics guys were passing out good wing designs, the aerospace
designers were all out drinking beer, which is why every airplane since the
Wright flyer has camber when they could have just used flat plywood.
