NASA's explanation of how the "Longer Path", or "Equal Transit Time" theory is incorrect. http://www.grc.nasa.gov/WWW/K-12/airplane/wrong1.html http://www.grc.nasa.gov/WWW/K-12/airplane/wrong1.html The page contains a simulator of a symmetrical airfoil that you can tweek, angle of attack, particle flow, velocity, and pressure - as well as instructions for experiments proving this theory incorrect.
