Saucer/disklike craft, with multi-colored lights sighted in Bayridge Brooklyn in 1970 with many eyewitnesses.

During an evening in early fall, when I was ten, I was outdoors playing on the sidewalk in front of our storefront apartment on 8th Avenue and 47th Street in Brooklyn, New York with some girlfriends. The avenue was bustling with people and motorists. A passenger bus was approaching....suddenly a humming sound caused us to look upwards towards the night sky. A strange lighted object shot down very fast and hovered across the street from my home above some buildings. It reminded me of the saucer from Lost in Space...the craft with very bright and colored lights went clockwise. As the saucer turned its angle a bottom set of colored lights shone displaying a smaller disk which was attached and the lights were going in a counterclockwise motion. The saucer (or disk) remained hovering for about 1 min. Suddenly it shot out into the sky and disappeared completely.
Date is approximate.  PD
