how does a fighter plane fly upside down?
Pretty well.
Fighters and other airplanes designed for aerobatic maneuvers have
airfoils that are, or nearly are, symetric.
The result of this is the majority of the lift is produced by the
angle of attack and less by the intrinsic shape of the airfoil.
For such wings the angle of incidence is usually much greater than
that of more asymetrical airfoils so that in normal flight the fuselage
is level.
When in inverted level flight, the angle of attack plus the angle of
incidence produces a pronounced nose up attitude of the fuselage.
A wing need not have an airfoil to produce lift. Witness the cheap
balsa gliders with flat, plank wings.
