@JohnShirley2023 Interesting. The only terrestrial power I can imagine being capable of such things is China -- now that we've seen just how worthlessly corrupt Russian miltech industry is. The cheesy balloons don't exactly suggest it's China either, unless that's a very clever misdirection indeed.
@JohnShirley2023 Well the ones they're selling to Russia are pretty basic, and reportedly people are stealing Rotax light aircraft engines from small European airfields to sell to them.
I'd need a lot of persuading that they (or NK) have anything that would surprise us technologically.
@pieist North Korea also possible.
@pieist Iran is known to have extensive use of and experimentation with drones.
