I swear this craft just appeared over my head. I can say for certain I saw lights at each one of the three corners of the craft and at least one on each of the sides. I did see what appeared to be either a large light or a window directly in the centre of the triangle. The eerie part was the silence for a craft hovering so close. It disappeared just as suddenly as it appeared and was gone again without any visible movement. It was pretty creepy.
The photograph (31k .jpg) is reportedly from Petit-Rechain, Belgium, the report is from near Edwards Air Force Base.
The Petit-Rechain photograph was apparently taken during April 1990, by a young Belgian who did not seek any publicity or financial gain. It was examined at the Royal Military School, Brussels and was not considered to be a hoax. This computer enhancement (36k .jpg) indicates that the object is not strictly triangular shaped, as may appear to observers, but delta shaped.
