Business as usual, we had an “oopsie missile” that destroyed a small neighbourhood of vacation homes once: https://da.wikipedia.org/wiki/Hovsa-missilet

DeepL translation:

The Hovsa missile was a Harpoon missile that was accidentally fired by the frigate Peder Skram at noon on September 6, 1982 from the southern part of the Kattegat.

After about 34 kilometers of flight at low altitude, the missile weighing more than 500 kg with an explosive charge of more than 200 kg hit some trees in a cottage area near Lumsås, Sønderstrand in northwest Zealand. At 11:32, the missile exploded at a height of approximately five meters at the boundary between the two holiday homes, Pilelunden 2 and Søndre Strandvej 3. Beforehand, it had torn several power lines. No one was injured in the accident, but four holiday homes were totally damaged, while 130 others suffered damage to a greater or lesser extent.
