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

They are flying within the air, not on top of it. So being upside down in a plane in air is like a person being upside down in water. That’s how I think about it.
