We were in a boat fishing at Lake Ray Hubbard, heading toward north end of lake. We noticed an object hovering just above a water tower on the east shoreline. It was dark and appeared triangular shaped. As we were returning from the north, we looked at the water tower and the object was gone. Just at that moment I looked back toward the north, and coming straight toward us at an altitude of 100-200 feet was a triangular shaped object. I would guess that each side of the triangle was about 50 feet, and that the object was traveling about 20mph. It passed directly overhead, and what was spectacular about it is that we cut the engine, and there was no sound from the object. Secondly, all around the edges were red, white and blue lights, pulsating intensely. We watched it as it slowly moved out of sight to the south. When we got back to the marina, we walked out on a dock to watch the sky. Lo and behold, we looked west toward the Dallas skyline and saw three of these objects sitting still in the sky in a triangular formation. Angle was about 25%. I was very excited and expected the radio stations and newspapers to be full of sighting reports, but never saw or heard a word. It was quite an experience.
