In 1957, not long after Roswell, a small, copper-colored flying saucer crash landed in a village near Scarborough, England. Three friends were driving by the Silpho Moor when they saw the crashing object, which to them looked like a falling, red star. Coincidentally, their car abruptly stopped working. One of the friends, Fred Taylor, then left the stranded vehicle to have a look at the crash site. Taylor was lucky enough to stumble across a "mini" flying saucer, however when he tried to pick it up, he was surprised at how heavy the object was, likely 50 to 60 pounds.
Taylor was actually not able to retrieve the object at the time, due to its surprising weight, but eventually the physical evidence came to light.
The metal disc was nearly impossible to pry open, but it was worth the effort. Inside was a tiny book with 17 copper pages containing hieroglyphs, which were later and roughly translated to be an alien's warning to humankind to stop their violent ways.
Unfortunately, the Silpho Moor saucer mysteriously disappeared, and has not been seen since.
Pieces of the famous saucer were just recently discovered hiding in the archives of a science museum, according to many news sources, including the BBC.
Some claim the UFO fragments have been tested and were proven to be of Earthly origin, and even suggest the UFO to be a hoax. UFO researchers may note many "markers" of this UFO case that give it some credibility, however, like the appearance of hieroglyphs (also seen on the Roswell UFO debris, and by witnesses of the Rendlesham UFO) and the witness' car malfunctioning (also common near UFO sightings, like in the Cash-Landrum incident in the 1980s in Texas).
As well, even if the Silpho Moor flying saucer did not have the expected exotic material, that doesn't really prove that a hoax occurred. Just that the "alien" theory could be an oversimplified one. Consider this; if UFOs are real but are not of extraterrestrial origin, could they be of unknown terrestrial origin? Could there be "aliens" living among us?
