Ok, since no one knows what this is, I'll wrap it up: Ernst Heinkel and Claude Dornierstand before one of their first creations: the HeDo-1. Made from a painters scaffold and some discarded paper tube rolls, pieces were bent to fit as that was easier than calculating necessary lengths. The downward turned wingtips created vortices that improved lift and trapped ground effect, while the upperwardly curved lower outer sections provided a comfy spot for passengers on long flights. Although almost finished before the Wrights first flew, in a grand display of sportsmanship and perfectionism it wasn't actually flown until 1987, when duct tape technology had advanced enough to be used to cover the wing ribs. It was broken up in 1995 - the old fabric covering then repurposed for wallpaper.
Thank you.
The research to supply this answer was difficult but not impossible. I don't know why y'all couldn't get it earlier... 😉
