How do we know when watching a black triangle shaped UFO with three lights on each of its triangles is a UFO or backed by the federal government TR-3B program. The answer is that we do not know.
When one of them is witness, shock sets in and disbelief, and fear. And, seeking shelter and safety is the best approach.
The black triangle shaped UFO was moving to the west, no sounds, at 800-1,000 ft and appear to move slow enough to be noticed.
In Royorsford PA, one was spotted by a couple in January 2013.
From MUFON Case No. 62573
Some of the best footage to date of the infamous and elusive black triangle has been submitted to MUFON on today, the 12th of January. The sighting took place in Royorsford, Pennsylvania back in July of 2013 when the witness states that they were driving home from the local 7/11 on a warm summer night. The witness reports seeing the triangular object hovering over houses that were around 3,500 sq. feet in size, to give a size reference to the object. The viewer was not alone however, and had two other witnesses with him or her in the vehicle.
