Six bright lights in "V" formation seen in Westport Mass USA in August, 1969.

I'm reporting an incident that happened 50 years ago in 1969 when I was 15.  Due to my age, I was afraid to say anything- especially to my parents.  Later, I became a government employee with a security clearance so I never reported it.  I have thought about this almost every day of my life.  Here are the details:  Date:  Mid-August, 1969  Location:  Westport Mass., Brayton Point Road on the eastern side of the southern end near the ocean,  Time: Mid to late afternoon (15:00-17:00)  
Friends and I were in the back yard of a home on Brayton Point Road directly on the water facing east.   For no reason, I happened to look into the sky in that direction and saw bright lights in a “V” formation over the water in the proximity of Mummy Rock- a rock formation in the water that resembles a reposed mummy.  There were six lights suspended in the air.  It wasn’t a plane because it didn’t move.  It wasn’t the Concorde jet because there was no sound.  They were not as high as the clouds.  They did not move and in a few seconds, they disappeared randomly, one by one, into thin air.  I looked over at my friends who were busy talking and facing in the opposite direction.  I could tell they didn’t see it. 
I couldn’t talk and was too afraid to say anything.  To this day I never have.
I would like to know if there’s a way to find out if anyone has ever reported this.  Thank you.
