not sure entirely of year it was but it was a clear blue sky day and i was about 13 me and my playmate were sitting on a haystack and i noticed three silver spheres in a triangular formation stationary in the sky, and even at that age i knew it wasnt manmade hardware. every now and again one of the spheres would shoot off at an impossible speed and stop stationary, stop dead suddenly not slow down. they all did this randomly and always returned bacck to the other two to form triangular formation. as far as i remember we watched for around half an hour, and cant remember if they dissapeared or we just quit looking. i have seen documentarys on tv where someone has described the exact same thing and it was around the same era.
