Diamond shaped UFO caught in Brazil on December 2016

On December 5, 2016, an impressive video of a bright UFO has been caught somewhere in Brasil. On it, we can a lozenge-shaped object appear and disappear in the sky. What is it?

Scott C. Waring explains:

Here is a video posted on Youtube by user Gagare1952. The video shows a UFO that is making a cloud trail. Its telepathic emotion sensors realised that someone had noticed it, so it immediately cloaked...as you see in the video below.

Have you ever seen such a UFO in the sky, only to have it disappear with seconds of noticing it? Yes, you have, and so have most the population on Earth. Out of sight, out of mind.
