How do planes fly upside-down?

Question

I understand that the wing of the plane creates downforce, lifting the plane into the air, so how do planes fly upside-down? Wouldn’t the wings start pushing the plane down into the ground once flipped?

Answer 1

Commercial airplanes are built to fly efficiently and rely heavily on the shape of their wings. They generally cannot fly upside-down despite what various movies might claim. Acrobatic planes are made with more symmetrical wings so that it is easier to fly upside-down.

And… Someone correct me if I’m wrong, but it isn’t the wing of the plane creating downforce. The increased speed of the air going *over* the wing creates a low pressure area, lifting the wing.
