Military pilots reported a low-flying triangular UFO flying just 500 feet overhead. It was evening, but there was enough light in the sky for them to observe it in detail. It had no vertical stabilizer and had a row of pulsating white lights along its trailing edge. Flying with it was a smaller craft.
One witness said that he could see seams in the dull black material the object was made of, but no regulation anti-collision lights.
The description is similar to hundreds of others about dark colored, low flying slow triangles, and another example of how these objects just don't go away, and neither are they explained.
