"Some of these sprays have metal flakes in them that make aerial craft invisible to radar. Spoofer sprays. Sprays like these can be used to create colorful, magnetized plasmas to cloak fighter jets."
Today I saw a big shadow moving across the ground shaped like an airplane. So I looked up in the sky because I wanted to see the craft that was causing it. But the sky was absolutely clear blue and there was no airplane anywhere to be seen. Not a cloud in the sky either. It was perfectly blue and all clear. It was one of the strangest things I have ever seen. The thing had to be really close to the ground because the shadow was 2-3 times longer than a car. It was moving along next to the highway.
