Mind-blowing footage' has emerged that appears to show a UFO flying over a US military base.
The clip - which shows a mystery object in the sky - was filmed by a couple in Dayton, Ohio, as they were watching the sunset from their home.
The pair are clearly shocked by the sight of the 'craft' floating in the air with its pointed end and strange markings.
The woman, who is filming the scene on her phone, asks: "What the f*** is that?", before adding: "It looks like it's moving with the clouds."
Someone else can be heard saying: "That's f***ing crazy."
The camera zooms in on the dark object - before it fades into the clouds.
Another onlooker is heard saying: "Oh my god, it f****** disappeared."
The clip was sent to Secure Team 10 , who describe themselves on their Twitter page as: "bringing exposure of the alien phenomenon and those trying to hide it back to the masses".
Owner Tyler Glockner can be heard commenting on the video, calling it "mind-blowing footage".
He claims that this is the third sighting of the same object by "three separate sources".
Another 'source' sent Secure Team a photo that apparently showed the same 'UFO'
Showing photos of a spookily similar object previously snapped in the same area, he says: "It's the same UFO. I am simply amazed, we have someone corroborating this sighting."
The video - which was filmed on Wednesday May 25 - was captured near the Wright-Patterson Air Force Base, which is ten miles from Drayton.
Tales of crashed UFO parts and alien bodies have been told about Wright-Patterson since 1947.
Between 1947 and 1969, the Air Force recorded 12,618 sightings of strange phenomena - with 701 of them classed as "unidentified", USA Today reports.
These sightings were recorded in Project Blue Book, the Air Force's files on UFO sightings and investigations.
Headquartered at Wright-Patterson Air Force Base, the programme was reportedly comprising only a handful of staff.
It came to light in 2015, when amateur historian John Greenewald posted more than 100,000 pages of the documents to his website The Black Vault.
He had spent nearly two decades requesting declassified information from the US government regarding UFOs.
Started in 1952, the project was given a termination order in December 1969 - and all activity under the study ceased in January 1970.
At the end of this latest video, Glockner adds: "There is no doubt in my mind this is either an alien craft or a very very strange drone - which I highly doubt."
He also suggests a third possibility: "A back engineered alien craft that's being tested by some black project over at Wright-Patterson Air Force Base."
