I remember telling my Dad that the Wright Brothers did not have a cambered wing - just flat like my Kites. It was also too hard to build a Kite with a cambered surface. And when I got into model airplanes we had a flat wing which also flew...
We went down the rabbit hole of trying to discover why ( back in the days before internet). The local library was where i found the answer.
Or just fly higher than the usual Big jet traffic in the area?. The smaller jets seem to have a higher ceiling?. Though i understand it may not be available.
