Danes Torpedo a Town

December 6, 1982, a Danish frigate the HDMS Peder Skram accidentally fired a harpoon missile during maneuvers in the Kattegat. The missile traveled 34 kilometers at low level and managed to take out several power lines before striking some trees and exploding. The fireball and subsequent shock wave destroyed four (thankfully) unoccupied summer cottages and damaged a further 130 buildings in the immediate vicinity. No human injury was reported.

The cause was a technical malfunction, as the launch key was not even activated. What?! This is what happens when software goes rogue. Just ask the Ariane 5 rocket…
