British Meteor aircraft encountered a UFO near Topcliffe, 1952
On September 19, 1952, at around 11 am, it is believed that a silver disc-shaped object followed a Gloster Meteor which was returning to RAF Topcliffe. Observers on the ground stated that it rotated whilst hovering, before travelling in a westerly direction and a very high speed.
This sighting is now associated with ‘Operation Mainbrace’, which was a large scale naval operation which attracted the attention of multiple UFOs, the one being seen at Topcliffe being just one of many UFO sightings from September 14-25.
A UFO was found on Silpho Moor, Scarborough, 1957
In 1957, it was reported that a small ‘copper-bottomed flying saucer’, believed to be around 18 inches, was found on Silpho Moor, near Scarborough.
This evidence being part of a UFO was widely controversial and disputed, with many believing the copper parts originated from earth.
However, these mysterious findings, which reports suggested contained thin copper sheets which were engraved with hieroglyphics, sparked wide intrigue.
These shards were recently found in the Science Museum archives and were then re-examined after archivists were told of their past significance.
