UFO incidents take on many shapes and sizes, and this incident that occurred on January 23, 1974, is a wild one. The Berwyn Mountains in Llandrillo, Merionethshire, Wales, was the site of loud noises, bright lights, and a possible UFO crash that was covered up by the British government. However, skeptics believe that the area simply suffered a 3.5 magnitude earthquake.

Later, declassified Ministry of Defence documents revealed that a meteor struck the area, only adding to theories about a possible UFO.

On October 12, 1978, Nancy Spungen went from being the notorious girlfriend of Sex Pistols bassists Sid Vicious to a victim of a horrific stabbing in New York City's Chelsea Hotel. Spungen was only 20 when she and Vicious were partying with members of the local punk scene. A deluge of drugs and alcohol makes it impossible to know exactly what happened on the night of her death, but while Vicious was pinned with the murder it's theorized that a local drug dealer stabbed Spungen in the abdomen before fleeing the scene and leaving Vicious to take the wrap. Vicious never served time for the murder. He passed away from a drug overdose not long after Spungen's death.
