Shag Harbour is a small rural fishing community located on the south shore of Nova Scotia, with a population of around 400 to 500 people. The primary source of employment in the area is the lobster fishery, which operates from November to May. Additionally, Shag Harbour is known for being home to one of Canada’s greatest mysteries.
Later that evening, the MV Nickerson from Sambro, Nova Scotia, reported seeing four bright objects arranged in a rectangular formation. The onboard Decca radar confirmed the presence of the objects, indicating that they were stationary. Captain Leo Howard Mersey reported the incident to the RCMP and also communicated with the rescue coordination centre and the harbour master in Halifax for an explanation of what he had observed.
On that evening, numerous separate sightings of yellow-orange lights in the sky were reportedfrom Halifax all the way to Shag Harbour. Local newspapers and radio stations in Halifax shared many eyewitness accounts of strange, glowing lights in the area around 10 PM.
At approximately 11:20 PM, reports began to surface regarding an object crashing into the waters of Shag Harbour. At least 11 witnesses described seeing a low-flying, bright object that appeared to hover and move slowly about 8 feet above the water’s surface before submerging several minutes later. Many witnesses noted associated sounds connected to the object’s appearance, including a whistling sound similar to a bomb dropping, followed by a whoosh, and finally, a loud bang.
Reports were filed with the RCMP, and two police officers who responded to the call ended up being witnesses themselves. There were also reports of an object floating on the water’s surface in Shag Harbour. Many in the area believed the incident involved a plane crash. Local residents and authorities quickly organized a search and rescue mission for any survivors. However, nothing was found that night except for a thick yellow-orange foam that stretched half a mile along the water’s surface where the object had been seen. Fishermen reported a sulfur-like smell in the vicinity of the foam.
In the following days, an extensive search was conducted involving the Canadian Coast Guard, the RCMP, local fishermen, and divers. The military, along with U.S. counterparts, became involved, including a dive team that reportedly discovered an object on the ocean floor. However, official reports indicated no trace of the object was found.
The Barrington Radar Centre, located nearby, collaborated the witness accounts, having detected the object(s) on radar. A former employee whose identity has been protected as a whistleblower reported that everyone involved in the incident that night was sworn to secrecy regarding what the radar had detected. In fact, two separate objects were identified: one was associated with the crashed object, and the other attended to it before both left the crash site, remains submerged.
To date, this incident remains a mystery. There are enough eyewitness accounts to say beyond a reasonable doubt that something definitely was seen in the sky that night around the area of Shag Harbour. The greatest mystery is “What was it?”.
There is a great documentary that has more details about the incident with eyewitness interviews. I highly recommend watching it. Please see below:
