unbelievable, seen in 1967 north royalton,ohio

disk came right over our house at 12:30 am. i was in back yard cleaning up. looked up to the southwest and was shocked !! there was this huge flying disc coming towards me. it had different colored lights moving around outside edge. size was about 300 feet across and it was about 300 feet high in air. went from west to east. it had like a angled dome on bottom with what looked like lit windows. absolutely quiet, no noise at all. it seemed to be moving about 25 mph. i ran in house to get wife, she saw it too. all these years nobody really believed us. only reason i am writing now is to find out if anyone else ever reported seeing something in my area at that time.
thank you,
ben
