“Shadows against a clear blue sky? Probably photod against a blue table cloth. I call BS.”
Its real. I can’t find the link right now but you can buy those off the shelf. They are auto-piloted using built in GPS. Just tell it where to go using a computer interface and it flies itself to that point. It’s also programmable for fairly complex flight plans.
They come with options for cameras and other light payloads.
Makes a person wonder if Moslems in the US already have some form of weaponized drones that could say carry a biological agent into a theme park or something.
Personally I would definitely address the issue of an anti-drone defense net in key locations, especially outside public events.
