The Lookout Air Raids were minor, but historic, World War II Japanese air raids that occurred in the mountains of Oregon, several miles outside Brookings. On September 9, 1942, a Japanese Yokosuka E14Y floatplane launched from a Japanese submarine and dropped two incendiary bombs with the intention of starting a forest fire. Thanks to a patrol of fire lookouts and favorable weather conditions the damage done by the attack was minor. The attack was the first and only time the continental United States was bombed by an enemy aircraft.
