A Canadian diver's discovery of a mysterious object off the coast of British Columbia has prompted a naval investigation into whether it is a lost nuclear bomb from the Cold War era.
Sean Smyrichinsky was diving near Haida Gwaii when he encountered a large, bowl-shaped object with bolts the size of basketballs. Initially thinking he had found a UFO, he later learned from a local that it might be a Mark IV nuclear bomb that went missing in 1950.
The bomb was aboard a US Air Force B-36 bomber that crashed after three engines caught fire during a training flight. The crew jettisoned the bomb over the Pacific before abandoning the aircraft. US military reports state the bomb was a dummy containing lead rather than a plutonium core.
Smyrichinsky reported his find to Canada's Department of National Defence, which expressed keen interest. The Canadian Armed Forces announced that a navy ship will be deployed in the coming weeks to investigate the object and assess any potential risk.
