A "Hershey bar" wing? You win the aviation division of the Internet! Not a lot of "ground pounders" will get the joke!
We own a 1969 Piper Cherokee with a "Hershey Bar" wing. We also have a homebuilt airplane with a constant chord non-tapering rectangular wing. But these days most Hershey bars have actually lost their aerodynamic shape.
A proud Cherokee owner.
