Strange lights have been spotted in the night sky over Devon, which UFO hunters believe are proof that aliens or the government are conducting anti-gravity flights.
A popular UFO hunting YouTube channel has uploaded footage of an encounter by a bus driver showing a bizarre triangular shaped object.
But one leading expert believes that a more down to Earth explanation, like a drone or Chinese lanterns, is more likely.
The video, which appears to show a spinning triangle of lights above Exmouth, in east Devon, was captured by a bus driver who was on a break.
Speaking to UFO website Mufon, the unknown driver is reported to have said: 'I was taking to my best man about my upcoming wedding on the phone.
'I would normally be in our restroom, but since the clock in the restroom was fast I had gone out early to wait while still chatting to my friend.
'While I was talking, I was just kind of walking about near the leisure centre, where my bus stops, when I looked randomly over in the direction of the river, which is when I saw the three lights in a triangle pattern rotating on its axis and wobbling slightly.'
A video discussing the object, which was spotted at around 9:40 pm on April 17 this year, was uploaded to YouTube by UFO Hunters Secure Team 10 earlier this week.
There, it is argued that the craft, known as a TR3B among UFOlogists, is likely of alien or governmental origin.
Many of the 'spacecraft' captured on amateur footage over they years appear to hover and move at great speed in any direction, according to conspiracy theorists.
They usually do so silently, leading the UFO community to conclude that they do not use conventional methods of propulsion.
This could theoretically free it from gravity's clutches and allow it to move in the unusual manner of a UFO.
Speaking in the video, Tyler Glockner from the channel, which has almost a million subscribers, said: 'They've been linked to secret government projects but we've also seen these things in space, so I guess the jury is still out on who owns them and who is operating them.
'I'd wager a guess to say that we both are. There are people outside the planet that have craft like these and the US government has these craft as well.
'This same object has been spotted multiple times. I think there's something strange going on above England.'
But not everyone is convinced that the footage shows anything sinister.
Alien expert and author of the UFO Investigations Manual Nigel Watson believes a more simple explanation is likely.
Speaking to MailOnline, he said: 'The objects are hard to distinguish due to lack of detail.
'Three lights can imply a triangular structure behind them, but in this case the lights seem to be moving about as if they are linked together or flying in close proximity to each other.
'They are silent so they couldn't be caused by an helicopter or conventional aircraft.
'There is a possibility that they are attached to a drone or three drones, or that they are Chinese lanterns that often look as if they are in formation and move swiftly and silently in the night sky.
'I think those possibilities or more likely than them being the lights of an alien spacecraft or a secret aircraft being tested over England.'
