I'll see your microcopter and raise you a forty year-old micro ornithopter. Like the miniature helicopter I fly today, outdoor duty for this bespoke dragonfly was precluded by even the slightest breeze, and so the project was canceled. There have been various rumors of bugs the size of, well, bugs for at least the past decade. Considering what unlimited cash could bring to the table forty years ago, I can't help but think modern versions are probably much smaller than even that.
