An American Bomber-36 crashed near British Colombia carrying an atom bomb in 1950 during the cold war. American authorities tried their best to locate Mark IV, the five tonnes atom bomb but failed to find it.
Now after 66 years a fisherman Sean Smyrichinsky was swimming near Haida Gwaii, which 80 km away from cost of British Colombia, when he found a strange thing in the bottom of the sea.
He told his friends that I have found something that may relate to aliens, something like a UFO. He said the thing was 12 feet long, consisting of bolts that were as big as basket balls.
An old man then suggested it might be the atom bomb that have been lost. He searched online and when he saw the pictures of atom bomb he was confirmed that he saw nothing but that atom bomb.
He contacted Canadian Navy who is going to deploy their forces in the area to locate the bomb using information from Sean.
