I'm highly skeptical about that dragonfly from the 70s. I think it's a mock-up at best, there's no way they made something useful for surveillance etc the size of a large dragonfly. Not in the 70s. Researchers working on this for decades can barely do this today!
- grandalf 16y agoI'm guessing all it did was fly around loosely controlled if at all. The miniaturization is impressive, but they were not likely able to do much more than a small internal combustion engine in the 70s. Today however I would not be surprised if such devices exist and are in practical use.
