Theoretically, it should be possible to measure the weight of a flying object from far below that object - by measuring the air that object displaced when it pushes on the ground. I HAD to know if this was realistically possible, so I set about building a very large scale to measure paper airplanes and flying playing cards. After getting successful measurements, I decided to go full scale with real airplanes.

bonus points to @noquarter7 for the relevant nerd snipe in last video's comments...
