Approx 5pm Monday 17th August 2015 saw approx 5 oblong (horizontal) silver ufos moving north ...at regular intervals (each one at different times) they would "blink-out" (go invisible) and then reappear. .but continuing in the line of direction they were going...I could see them for approx 1 minute before lost sight of them because of trees. It was a clear blue sky ..no sound..they had a kind of serenity about them in the formation....just moving along easily.
