Airplanes do not fly by pushing air down. (FALSE, wings push air DOWN)
Airplanes fly by pushing air up. (FALSE, the ROUND leading edge pushes air BOTH UP and DOWN, mostly down) If any plane pushes air up, then it is going DOWN.
Look at the shape of a wing, flat on bottom and curved over the top. (TRUE to supply lift) If it was curved over the bottom -> NO LIFT!
The ANGLE of the bottom edge connected to the plane is PITCHED upward and pushes MORE air downward. More AIR is pushed below the plane than above.
The Flat surface does not push air down but the curved surface pushes air up. (FALSE, impossible)
The wing displace the same amount of air over both top and bottom surfaces. (FALSE)
With the air going over the top, it need to travel a greater distance so the air pressure is lower. (FALSE)
The pressure differential pushes the wing up and the wing pushes the plane up. That is lift. (TRUE)
Planes have lift due to constant acceleration. (FALSE)
----------------------------------
Almost EVERYTHING written ABOVE about AIRPLANES is completely FALSE. Please don't believe it. I have already posted a website that explains why it is WRONG. I really am not sure why he would write it.
