The air through the rotor disk of a gyrocopter flows upward, yet
gyrocopters fly.


I wrote "helicopter" -- not gyrocopter.

They are not aerodynamically the same.

I know what you wrote and I know they are not the same.

The point is that any theory that says an aircraft flys by forcing
air downward fails to explain how gyrocopters and gyroplanes fly.

Airplanes, helicopters, gyrocopters, and gyroplanes all fly in
level flight due to the lift produced by the wings and/or rotor blades.
