Alien conspiracy theorists claim unmarked black helicopters are often seen in the vicinity of UFO sightings.
The theory being that the choppers belong to the so-called “Men in Balck” – an alleged secretive government department whose staff try to hush up evidence of aliens visiting earth to avoid the public finding out.
The three bizarre objects that the husband thought were military flares.
In their report to MUFON, the unnamed woman said: “My husband is a long-haul truck driver and we were on a run from Washington State to Albuquerque.”
She said they left the town of Beatty, Nevada, heading south on SR 95.
“My husband thought they were military flairs. I say that they are UFOs.
“We took pictures and watched them just hover there the whole time.
She added: “The next day outside Boulder City, Nevada at about 6am we videoed 15 black Helicopters flying in the direction of where we saw the objects the night before.”
MUFON is investigating the allegations.
He also said that the three so-called UFOs were actually just contrails left by planes which were lit up by sunlight.
