The UFO sighted over the Windermere area of Cumbria was described at the time as triangular or diamond-shaped and rather like a twin-hulled catamaran. It seemed to have some respect for the British road system too, hovering for some time above the A592, one witness said, then disappearing into the night sky over nearby Morecambe shortly after midnight on 28 August 1977.
Though some began questioning the strength of the local ale, dozens of witnesses including 10 police officers were adamant they had seen the object. Their story of its charcoal colour and two giant lights remains one of Britain's legendary UFO stories.
Yet if the truth is still out there over the Lake District, the means to engage with it may soon be gone. Gloomy about the fast-diminishing number of sightings, the Cumbrian branch of the British UFO Hunters has declared itself ready to call it a day.
Sightings of UFOs have fallen from 60 in 2003 to none this year. Chris Parr, of Whitehaven, a ufologist and branch member, said the end of Mulder, Scully and The X-Files on television had brought the beginning of the end to UFO-spotting.
"It's also to do with a lack of military exercises in the area," Mr Parr added, expounding a theory that 90 per cent of UFOs can be explained by "secret military projects". He said he got his information from "UFO spotters hanging around outside military bases and breaking into them".
He added: "The number of people keeping their eyes on the skies is greatly diminished. There are only a handful of us now. I have three camcorders and a digital video and I start recording whenever there have been sightings in another part of the country."
A year ago, UFO Magazine closed down after a 25-year run, having once enjoyed a sale of 35,000 copies, which made it the world's top UFO publication. Suggestions of paranormal interference in the publishing decision were ruled out. It was more to do with the death of Graham Birdsall, the editor and world UFO expert who, along with his younger brother Mark, founded the Leeds-based publication in 1981.
Before that had come the death of former diplomat Gordon Creighton, 92, who was editor of Flying Saucer Review, the longest-running UFO magazine.
Andy Roberts, an author of UFO books and former magazine contributor, said: "Ufology is really a thing of the past century. The end of The X-Files series didn't help, and there has been a decline since the televised alien autopsy of the mid-1990s. Basically, it was a hobby that broke into the mainstream. Ultimately, there was only a hardcore following."
But the picture is not entirely bleak. West Kilbride, in Ayrshire, has topped the league for the number of close encounters of a strange kind with 12 recorded sightings last year, three times as many as its closest rival.
UFO enthusiasts are also excited about the Penzance Triangle, a 226sq-mile area of Cornwall between Land's End, St Ives and the Helford Estuary, where you are twice as likely to spot a UFO and three times more likely to see a ghost, than in the rest of the UK, some say.
Then there is the submission to the British UFO Research Association website, headlined "Extraordinary events in Cumbria" which tells of a "ball of light and vehicle interference" last New Year's Eve at Hethersgill, near Carlisle.
The Barrow Evening Mail, which broke the story, came under e-mail attack from as far away as the United States. "Stop the propaganda," wrote an American. "Everyone knows UFOs come in flaps and waves."Reuse content
