On Saturday, August 1~ we were c ed on the southeast side or Benson Lak~. ~t 8:15a.m. that day we ere sitting by the edge of the lake, which was very calm and quiet, when we both heard a brief sound of ruahing air. ~ were both surprised, for the branches of the trees did not move. '~hen we again heard the sound a few seconds later, we both looked up and I saw three objects moving fro east to west at an incredible speed--so Cast that before my friend could locate them, they had disappeared behind a cloud in the west. In the brief ~oments tt1~t l observed the, r waa able to clearly ~ee the three bri~htly silver objects moving on a parallel course, but at variable forward speeds. As one of t.he ooved ahead of the other two, there was an ad.iustment and they would line up for a mo~ent l>er~re another would g~t ~head, ~nd then the adju~tment would be 1en~ated.
