Seilbomb
A Seilbombe (German pronunciation: [ˈzaɪlbɔmbə], plural Seilbomben, [ˈzaɪlbɔmbən]), literally "rope bomb", was a secret German weapon developed during the Second World War designed to disable the electrical power grid of an invaded territory. Equipped with it, a German Messerschmitt Bf 110 fighter plane or an Arado 196 float plane would fly low at night over areas near enemy power plants or urban centers where power lines were located and would use it to cause local blackouts.
