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?

I got into this discussion in a similar thread, and one topic was Bernoulli’s principle (air moving faster over a larger surface area) versus Newtonian principle (angle of the wing).

Really, it comes down to the design of the plane…the wings, the flaps, the angles. Most planes aren’t designed to fly upsidown. Certainly not commercial passenger planes.
