World War II: Over 1,000 bombers attack the small island of Heligoland, Germany.

A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs, launch torpedoes, or deploy air-launched cruise missiles.

Heligoland is a small archipelago in the North Sea. The islands were historically possessions of Denmark, then became possessions of the United Kingdom from 1807 to 1890. Since 1890, they have been part of the German state of Schleswig-Holstein, although after World War II they were managed by the United Kingdom as part of the British occupation zone in Germany from 1945 to 1952.
