Over 50 years ago, on the night of 4 October, strange lights appeared over the sky of a small Canadian fishing village.
Witnesses watched as the lights flashed and then dived towards the dark waters off the coast of Nova Scotia.
Now, what some believe to have been a UFO sighting has been commemorated by the Royal Canadian Mint.
The mint has released a collector’s coin that tells the story of a “unique and mysterious event”.
The scene on the glow-in-the-dark coin depicts a specific moment described by various eyewitnesses.
After seeing four strange flashing lights in the offshore night sky, they spotted an object 60-feet in length flying low, which dropped down at a 45 degree angle.
It then made a “bright splash” as it hit the water, according to a defence department memo about the incident.
The Royal Canadian Mounted Police (RCMP), which had received numerous calls reporting a plane crash in the harbour, along with local fishermen, tried to reach the object before it sank.
Canada’s defence department later conducted an underwater search of the area where the object was seen entering the water, but failed to locate any evidence of an object.
