These ten drones most likely, almost certainly, were cxontrolled by ten individual operators. I do not dare to maginbe what high tch states do with autonomous drones - and swarm intelligence. To me, this outlook is a deeply worrying one since several years, since the first time I ever spend some thought on it and have read about it.
And I finally have to ask this: past tense of "to read" - is it "read" or "red"?
Certainly it is not "roed" LOL . I weasel around this case since long time...
