The Shag Harbour UFO incident, 1967 UFO sighting

The Shag Harbour UFO incident was the reported impact of an unknown large object into waters near Shag Harbour, Nova Scotia, a tiny fishing village on the Atlantic coast, on 4 October 1967. The reports were investigated by various Canadian civilian (RCMP and Canadian Coast Guard) and military (Canadian Forces navy and air force) agencies as well as the U.S. Condon Committee.

En route to Toronto while flying over Sherbrooke and Saint-Jean, Quebec at 3,658 metres (12,001 ft), from the Halifax International airport, Air Canada First Officer Robert Ralph pointed out to Captain Pierre Charbonneau on Flight 305 that there was something strange out the left side of the aircraft at 7:15 pm. In his report the captain reported an object tracking along on a parallel course a few miles away. He describes it as a brilliantly lit, rectangular object with a string of smaller lights trailing the object. At 7:19, the pilots noticed a sizable silent explosion near the large object; two minutes later, a second explosion occurred which faded to a blue cloud around the object.

Yellow object
Darrel Dorey, his sister Annette, and his mother were sitting on their front porch in Mahone Bay, when they noticed a large object manoeuvring above the southwestern horizon. The next day Darrell wrote a letter to RCAF Greenwood Base Commander asking what was flying over the water that evening, as he had never seen anything like it.

RCMP 67-400-23-X
While standing at the wheelhouse of his vessel, Captain Leo Howard Mersey was looking at four blips on his Decca radar that were stationary. When he looked up about 28 kilometres (17 mi) from the vessel's windows he could see the four bright objects situated in a roughly rectangular formation. The entire crew of nearly twenty fishermen stood on deck and watched the object in the northeastern sky. Mersey radioed the rescue coordination centre and the harbour master in Halifax asking for an explanation and filed a report with the Lunenburg RCMP outlining his sighting when they arrived in port.
