I am only in to about 5 minutes of this video. I know nothing about this topic. I will lived in a town that had a lot of travel via air and trains to an army base. My husband saw some unreal aircraft. It was huge and cigar shaped but had NO sound. Keep in mind this was also when the base put out that Trump had gotten upgraded military equipment/amno and they were testing them out! Therefore I believe our military has some very high tech machines that could look like a UFO. This doesn't mean I don't believe aliens exist it is just a thought.
