Would maybe make a decent twilight zone clip.
Naturally, folks reacted like it was a joke. ;)
(I may have been fascinated beforehand though—I had a small wind-up one as a kid.)
Kazuhiko Kakuta has a small YouTube channel where he experiments with ornithopter builds (and ornithopter adjacent craft): https://www.youtube.com/@BZH07614/videos
It's not that all birds aren't real.
But some birds definitely aren't real.
> The O1 drone weighs 1 pound and can fly up to 10 kilometers, which is a little more than 6 miles, for over an hour, according to a company fact sheet.
Nonetheless, it should possible for a flapping-wing drone to do some short-time gliding between intervals when it uses wing flapping to ascend to the initial height, in order to save some energy.
Drones' ability to absolutely dominate the battlefield inside of ~200km is just too powerful. You'll end up with small regional powers that are basically impregnable to invasion, but also can't project power because the range of drones is too short. City-states, basically. And because the defining characteristic of a state is its monopoly on physical force, the structure of the state will adapt to the dominant military technology of the time.
