In 1941, during World War II, a group of Nazi German soldiers led by Koenig used a piece of Chronosteel in southern England to block British radar, intending for a German fleet to reach England before "so-called British Intelligence" could suspect them. However, the Germans were thwarted by Clyde Langer and George Woods. (TV: Lost in Time)
