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?

Not ALL planes can. The speed, the shape and size/weight of the hull and wings define if it can.
A proper example how it can be is Ziv Nedevi that flew and landed F-15 with one wing. The plane was basically a rocket – long narrow hull, relatively small and straight wings, high speed.
Also take note that even if they can do it, they can do it only for a certain time and under certain conditions.
