The case of the Wilsthorpe Incident is being investigated after a number of witnesses to the bizarre events along a 25-mile stretch of the East Yorkshire and North Yorkshire coast were discovered.
Witnesses reported seeing strange lights, and odd-shaped craft in an area from Brandesburton in East Yorkshire to Scarborough, North Yorkshire, between May and September 2009.
In some cases UFOs were seen entering the sea, and cars ground to a halt as one appeared, it is claimed.
Two Chinook helicopters full of RAF personnel landed at the beach by the remote hamlet of Wilsthorpe, East Yorkshire, on Tuesday, September 15 2009, at the height of the sightings, paranormal researcher Paul Sinclair has revealed.
It was the day after a bizarre late-night sighting of between 30 and 40 UFOs in the same area by an elderly couple whose home overlooked the beach, he said.
The multiple UFOs sighting followed a spate of other strange UFO sightings along the area of coastline, Mr Sinclair told the Outer Limits Magazine 70 Years of the Modern UFO Era Conference in Hull.
The military action and UFOs were witnessed by the couple, several bait diggers, and a boat worker, a seven-year investigation by Mr Sinclair has discovered.
