UFO investigators are looking into a case when a man said he encountered a low flying, silent, triangle-shaped object along a rural road.
The man in Orrington, Maine, was driving with friends at 11.19pm local time when the incident happened.
He reported it the the US-based Mutual UFO Network (MUFON) which is investigating the growing phenomenon.
In a report to the organisation, which keeps a global database of UFO cases it investigates, the witness said: “We were heading up the Brewer Lake Road and went around an ‘S’ turn and we had noticed these red lights down the road above the dam on the lake.”
He initially thought it could be a plane from Bangor International Airport.
He added: “But there was something unusual about the lights.
“This triangular silhouette went from being far off the road and fairly high in the air (500 – 700 feet) to swooping in very close probably 400 feet off the road and 200 feet high.
“The way the object moved down closer was very odd and I was euphoric, but terrified at the same time.
“It was flat with the horizon when the object dipped up one side at 20 to 30 degrees and swooped in closer.
“The best way to describe it is the way a feather or a leaf falls to the ground and swoops side-to-side. After it swooped down close to the car everyone started to have this moment of awe, yet panicky.”
The man went on to describe a bizarre encounter that they tried to film.
He said: “We were all looking at the black equilateral triangle that had glowing bright red lights on each end.
“The object also had a centre light that glowed white and the object was dark against the clear night sky and it had to have been 40 to 60 feet across.
“But we looked at the video after and we couldn’t see anything but darkness.
“While she was filming, I kept almost driving my new car off the road into a ditch because this object seemed to be hovering closer to us.”
The group said they saw a second, larger triangular object in the sky.
The report added: “We turned the corner away from the UFO, and this bigger, triangular thing was across the lake above the Holden/Bucksport side of the lake heading towards the direction of the black triangle UFO.
“This could have been an aeroplane, but it was still dead silent.
“For weeks after I kept dreaming about that 4 or 5 minutes of my life and it was odd it happened on Friday the 13th.”
The incident was in January, but has just been reported to MUFON.
Maine MUFON Assistant State Director Valerie Shultz is investigating.
A MUFON spokesman said: “Please remember that most UFO sightings can be explained as something natural or man-made.”
In December Express.co.uk revealed the huge number of similar triangle UFO reports being made to MUFON.
The reports are often eerily similar, leading to speculation the bizarre UFOs could be REAL.
Many reports tell of a silent triangle shape, defined by a series of lights, that are said to be in some cases as big as a football field, moving slowly across the sky.
Scott Brando runs website ufoofinterest.org which exposes hoax UFO sightings.
He is sceptical any unexplainable sightings have been made.
Mr Brando says triangle UFOs are usually aircraft or military flares.
He told Express.co.uk: “About other similar sightings I’d like to see some reports by MUFON, however many formation of sky lanterns or the launch of skydivers Golden Knights were often mistaken for UFOs.”
