A California witness at Manteca reported watching a low flying, black triangle UFO crossing the sky silently, according to testimony in Case 81275 from the Mutual UFO Network (MUFON) witness reporting database.

The witness stepped into his backyard about 11:10 p.m. on December 31, 2016, to look for the New Year’s comet with a green laser pointer.
​
“Moon had already set,” the witness stated.“I just stopped playing with the laser and in the darkness and I noticed movement directly above me out of the corner of my eye.”
