Saw a bright light, then the light changed to three red flashing lights.We where watching a fireworks display in Sukagawa (Japan), when we saw this bright light. At first i thought it was a star, but it started to get bigger. "Oh it's just a Helicopter" i thought, but it did not have a red flashing light. Then it became more clearer, and you could see the shape more clearly. (shaped like a disk) Then the white light stopped and red lights started flashing (three red lights one after another), not like a planes red flashing light. These lights were going around the ship, not in one spot like a plane. The ship then started to move across the sky over our heads at a high speed (about five times faster than a plane). Then it just dissapeared. I have never seen anything like this before. There where many planes flying over head that night, but this was not a plane. Planes have a white and red flashing lights and you can see the out line of the plane as well.
