We saw 3 rectangle white lights in a horizontal line evenly spaced above badbury rings silently moving away from us .Then at the end of the avenue of trees hovering above the last tree on the left was another one which we realized when passing below it was a saucer ahape.Neither object made a sound .After passing under second ufo,and cresting the dip of the hill befor true lovers knot hill we saw in front of us a double rotar chinnock helicopter flying at about the same height of the saucer.Within two miles of the incident is blandford army base.I know what i saw that late afternoon.If it is ours,we the public dont know of its existence.
