I thought this was interesting. Especially since more than one of us has seen these. My photos are at the bottom.
It appears that cloud drones & artificial clouds are real. These are 2 different things. One is a new level of spy devices. The other is for weather modification & cooling.
This link says they saw a cloud drone with twinkling lights.
They also plan to use artificial clouds to cool an open top sports stadium. Clearly, they were too cheap to pay for a retracting roof & central heat and air system. The artificial clouds will likely cost more. It doesn’t look anything like a cloud. It is a flat rectangular helium filled structure with RC quad copters.
Then there are cloud seeding drones. Or drones which seed clouds.
It wouldn’t be that difficult to create a cloud drone. Just buy an RC quadcopter with a camera & video like the paparazzi use to obtain overhead photos of celebrities. Spray paint it white, then glue white trash bags & cotton or other white fluffy materials like fur or wool etc., on the bottom & sides to disguise it like a cloud. Something lightweight to not weigh down the drone. Ensure there is enough airflow for the RC drone quadcopter. Use the video Camera hidden on the bottom to guide it & take pictures. You can also include a GPS device, phone or Tom-tom. Be sure to blackout any lights on the device. Crushed frozen CO2, steam or insect foggers could also be adapted to create cloud cover.
A few years ago, I saw a single small cloud hovering over my yard lower than 100 ft (closer to 50 ft) high for 2-3 hours. The cloud was smaller than a house. Possibly smaller than a car. It was the only cloud in the sky. With the Earth rotation & air currents, it is impossible for a cloud to hover for 2-3 hours in one spot. Then it drifted away. I took photos of it & forgot about it until yesterday when one of our site visitors mentioned seeing one like it.
Also interesting was the weird cloud I mentioned seeing under the gatling gun lightning storm 3 weeks ago, which was exactly the same shape. Like one of the old shuttles on the Starship Enterprise. A Rhombus shape.
(when I mentioned this older cloud to my family member who retired from the CIA & then became a contract agent; he told me how they used to put cameras in fence posts at certain intersections. When I laughed about it, he walked down my road & showed me a hollowed out fence post with a Camera view hole less than 100 ft from my house.) They are always PO’ed about various issues I post for the public. Tough. Everything I post was obtained from freely available public info. Not my problem if their censors missed things.
Here is the photo of the cloud which hovered for 3 hours, I saw a few years ago. It was also silting some type of white powder. Very curious.
