A Florida witness at Naples reported watching a “mostly transparent” triangle-shaped object pass overhead that was followed by a black helicopter, according to testimony in Case 64601 from the Mutual UFO Network (MUFON) witness reporting database.
The incident occurred about 10:30 p.m. on October 18, 2014, when the witness was sitting on a balcony facing north.
“It had three visible circles, one on each point of the triangle, the edges rippled a little so you could just make out the edges of the craft, but the rest of it appeared transparent,” the witness stated.
The sighting was quickly followed by a black helicopter that had a light and made noise.
“It returned on exactly the same path, north to south, about 20 minutes later, but without a helicopter following.”
The witness believes the object may have been man-made.
It's certainly possible that it was man-made. To read more, click here.
