About two years ago....if you paid attention to drone development in China....they had gone some extremes on development. The drones were bigger, faster, and more capable of time aloft. They could also synchronize a hundred drones to work in tandem.
So the Chinese have some strategy where they entered the US with their hardware, and based literally dozens of teams with their drones....making Americans thinking of a UFO/UAP situation.
If this strategy advances? Well....imagine that you were a team of three guys with sixty drones....based out of Dayton, Ohio. Your drones have a carry-capability....so you could launch with a 10 KG explosive. So you arrange the sixty drones in a rural situation....fully charged-up and each is sent on a drop mission. Within 2 hours, they return....with sixty gas stations struck in the Dayton area, and for at least six weeks....they will all be non-op. On evening two, you target sixty logistical points.
Now imagine forty teams around US....with the same mission.
The bigger drones? You could have drones capable of carrying 200 KG of high explosive....for dropping on bridges, airport radars, or trains, or ships.
The fact that the Pentagon is caught flat-footed and unable to find or pursue these? Add to it....the border being open and zero interest by Homeland Security?
As much as the UFO/UAP scares the crap out of people....if this drone thing goes to the second strategy.....you've been invaded by a bigger worry.
