Another Triangle UFO Seen in California’s Triangle Alley

Proving once again that they don’t call it “Triangle Alley” for nothing, a triangular UFO was spotted recently over Yuba City, California, in an area known for sightings of three-sided UFOs of various sizes. What’s attracting these unique UFOs to this one location?

The anonymous witness was taking photographs of a thunderstorm on October 3rd, 2015, at the Boyd's Pump Boat Launch Facility on the west bank of the Feather River in Yuba City, located in California’s Sacramento Valley. After running out of memory space, the witness went home and returned with another SD card to the same location, where the following happened:

I got a weird feeling, like I should leave, that got quite intense and I was scared, but was not sure exactly why. When I got home I loaded my photos onto my computer and realized there were two different photos that had a strange and unexplainable object in them.

The witness contacted MUFON and added another sighting to its list of triangular UFOs seen in Triangle Alley – an area that runs south from Redding through Sacramento to Sonora and possibly all the way to Fresno, where this triangular UFO was observed in 2010.


More recently, an “enormous” dark triangle UFO with “bright lights, red, blue and lots of white” was seen by two witnesses in Livermore on September 14th, 2015.

Yuba City has had its share of UFO sightings of all shapes and sizes. A dark, slow-moving UFO with bright lights at either end was tracked by a witness on September 27, 2013, before it suddenly disappeared. This high-speed cigar-shaped UFO was photographed there in December 2010.

What could be attracting triangles and other UFOs to Yuba City? Here’s a possibility. On March 14, 1961, a B-52 Stratofortress carrying two Mark 39 (3.8 megatons each) thermonuclear bombs ran out of fuel and crashed near Yuba City. According to reports at the time and declassified documents released later, the aircraft was destroyed on impact and the bombs, which were ejected by the crew, disintegrated with no explosion and no release of radiation.

Are the UFOs some sort of aircraft that are continuing to monitor the area? Are they ours or someone else’s? Could they be ghosts of the B-52?

The triangle UFOs continue to visit Triangle Alley and their source remains unsolved for now.
