i saw a ugo near leiston nuclear facility a few years ago. a friend and i sat having a cigarette on break and some big white thing flew so quickly in front of us we both instinctively jumped up to see where it went. it was mental as fuck but obviously i can't prove it or say what it was. could have been the lighthouse up the coast for all i know. it definitely seemed like it's own thing, not a beam of light.
