I added focus and light to these two screenshots.
Date of sighting: Sept 29, 2020
Location of sighting: London, England
This UFO comes into focus really well at about 20 seconds into the video. When I took some screenshots and cleaned it up, I noticed its not a donut shape after all, but a disk shape with some white sections. The white sections are not see through but do appear to be crossing the center of the craft. Also a few flashes come from the white center of the craft. It tilts from left to right, but never flips over. Its speed is much faster than a balloon. I do believe this to be an alien disk. The white area is like a window cockpit area. I am really surprised there are no fighter jets investigating this craft.
