I saw an ufo! in was in d,c, for my friends' wedding and saw ufo over washingtorn monument upon walking home. there was a loud humming buzz that made us look that way. i assumed it was a helicopter but it was light up and glowing which helicopters don't do. then there was flashes of colored lights. it hoovered and then seemed to fade away. i felt confused and asked sharon (who got married!) if she saw that but she didnt see it because it was only there for a couple few seconds. after it fade away, 2 or three minuets later we are walking again and i felt a lot of wind and heard a helicopter flying over.
