Here’s one interesting footage of a very bright and fast object flying across the sky above Tver region, western of Moscow in Russia. This was filmed on August 7th 2016.
Witness report: This night ( 07 2016) i watched satellites and meteors in the night vision device. Suddenly i saw this very bright elongated object. Brightness of it is similar to the ISS. As usual, I checked it out on the basis of data Stellarium. This object is not in the Stellarium database Therefore, it is 100% UFO. Perhaps this is secret military satellite.
