Two UFOs were photographed Sunday afternoon, August 20, 2000 at 3:09 p.m. hovering on either side of the famous "Copse of Trees" (clump of trees) in Gettysburg, Pennsylvania. However, the UFOs were not visible to the witnesses or the photographer, but showed up later in the photograph.
Are those the first BLURFOs? The fact that the people did not see anything there visually suggests so.
