The John B. King explosion was a Canadian maritime disaster on June 26, 1930, when a drill boat containing dynamite was struck by lightning near Brockville, Ontario. Thirty people were killed. The scow was off the point of Cockburn Island working on blasting a St Lawrence Seaway channel through Brockville narrows, and had drilled several holes of dynamite. At 4:30 pm, while it was drilling another, a bolt of lightning struck the boat, travelling down the drill, and igniting the dynamite on the river floor.
