During the Cold War it was an important NATO base, stationing fighter jets to intercept Soviet naval vessels and aircraft. The situation culminated when Premier Kruschev threatened to destroy Bodø with nuclear weapons after a CIA U-2 spy plane bound for the city was shot down over the Soviet Union. You can learn more about the city's Cold War history at the Norwegian Aviation Museum, which is uniquely designed to resemble a biplane and houses an intact U-2 plane, a Spitfire, a rare Hønningstad C-5 polar seaplane and many other interesting exhibits. As well as its military heritage, Bodø boasts the world's strongest maelstrom at Saltstraumen, which attracts a host of visitors every year.
