Coamo (Puerto Rico) - Disk

Aproximately at 10:30 PM on Friday August 14 1964. I and 4 other friends we were on small valley sorrounded by small mountains we so this Flying Saucer shape object coming from the South and stop at this mountain about less than a quater of a smile away from where we were. The ship slow down at the mountain as if they were looking for something on the ground. All of us we kept quite and the ship was there for aproximately 30 minutes or so. The ship was following like a rectangular pattend at the top of the mountain. The ship never landed there, but after been there for that time it took off on a Northeast course, crossing the sky in a matter of about 30 seconds. That was very very fast. There were no noise coming from the ship. The following day we went to the mountain during the day to look around. The only thing we found at the top of the mountain was sea shells and brain coral like if the mountain at some point was under water. We didn't find any thing unsual. To this date some of the people that we were there still said: What was that thing that we so there. I guess we will never know. The only thing I can say is what ever that was, it was not from here. At that time that happen I was 14 years old, sometime ago. I will never ever forget the shape of the ship as longer as I live.
