Unidentified Flying Object in Diamond Shape over Washington D.C.

Summary

A witness in Washington D.C. observed a diamond-shaped object, dark grey with a pulsating orange-brown glow in the center. The object passed overhead, making no noise and showing no signs of wings, propellers, or exhaust. Two witnesses reported the same shape, though one did not specify colors. The object was sighted for a few minutes, but precise triangulation was not achieved. The detailed description and lack of conventional explanations make this an intriguing UFO case in history.
