In December 2018, multiple videos surfaced online appearing to show a massive pyramid-shaped UFO hovering over the Pentagon in Washington, D.C. The dark, triangular craft seemed to rotate silently in the night sky, witnessed by drivers and passersby near the city. While skeptics argue the footage was a CGI hoax, UFO researchers noted similarities to other reported sightings of black triangles and pyramid-shaped craft around sensitive military sites. The incident went viral, sparking debate about whether the Pentagon itself had been “visited” by one of the most extraordinary UFO forms ever recorded.
