An Unbelievable Throw?

Bullets do not rise from spin.
Airplanes do not fly by pushing air down.

All firearms are bore-sighted by aligning the angle of the barrel with the angle of the sight at a fixed point in the distance. Up until that point the bullet 'rises' due to the upward angle of the barrel in relation to the sight.
Airplanes fly by pusing air up. Look at the shape of a wing, flat on bottom and curved over the top. The Flat surface does not push air down but the curved surface pushes air up. The wing displace the same amount of air over both top and bottom surfaces. With the air going over the top, it need to travel a greater distance so the air pressure is lower. The pressure differential pushes the wing up and the wing pushes the plane up. That is lift.
Planes have lift due to constant accelration.
Baseball's and bullets have constant decelleration. Therefore, they fall.
