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

In a manner of speaking, most planes cannot *fly* upside down. They can go upside down once already flying.

High performance aircraft usually have high thrust to weight to keep enough angle of attack to generate lift upside down (wings still angled into the oncoming air).

Aircraft with thrust vectoring can pretty much do whatever they want (that’s where the engines can redirect thrust with the nozzle)
