Answer 1

Because that’s only part of why they fly.

Plane wings push air down, the air pushes the planes up.

Curved wings are more efficient at this as they can pull some air from above the wing and deflect it down.

But simply having tilted wings can push it down. So flying upside down is just as possible but less efficient when the wings make the proper angle with the airstream.
