The myth that won't die.
There it was on again, on "Nova" of all places, in a show about the Wright
brothers the night before the centennial.
The "Equal transit, air has to go farther over the top so it's faster" crap.
They even had the worst of the diagrams that usually accompany this
explanation. The air goes over the top of the wing and then turn abruptly
at the trailing edge to follow the flight path with no downwash at all.
The Wright brothers probably knew enough from their experiments and
observations that they would have laughed at this.
