On 6 September 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, severing several power lines before striking some trees after which it exploded. The fireball and subsequent shock wave destroyed four unoccupied summer cottages and damaged a further 130 buildings in the immediate vicinity.
