Looking up at the moon, mainly clear sky; moon very bright. walking home from work. as i was looking up noticed outline of black object over head, moving in straight line no sound at all. moving at a steady rate of speed, i would guess at approx. 100-200 mph. lost sight of object after 10 seconds one minute later observed another craft exact same shape and speed moving in the exact same direction. second craft had four lights, two on each side of triangle. lights were dim not bright, lost sight of craft after 10 seconds. one minute later observed another craft of exactly same shape and size moving in the same direction as the other two. lights on the third craft were brighter more clearly seen.
