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

The force created by a flat moving object pushing against the air, doesn’t care if it is “upside down”

Not wings themselves generate uplift, the wings cutting trough the air and creating high pressure on one side, low pressure on the other do.

Side doesn’t matter, the direction of the plane doesn’t matter.

If a plane flipped upside down, the “top” of the wing is thet is pushing against the air.
