You wanna see a "real airplane" wing section, look at say a L-1011 or DC-10, from root to tip.
Obviously inverted at the root, changing at the wing pylon to symmetrical to semi-symmetrical at the tip.
The aereon sprite in charge of pitching moments has his hands full on those wings! _
To say nothing of the structural stuff.
One of our "engineers" saw the cutout in the fuselage side on the first Tristar for the wing, and wrote a letter to the company president informing him the aeronautical engineers had the wing on upside down!
He knew this because he flew a Cessna and knew which way wings were supposed to curve!
He didn't last long.
