The V-1 "Buzz Bomb" was the first practical cruise missile in military history. Nazi Germany fired many at Allied population centers in the last year of World War II. One of two brought back to the United States at the end of the war ended up as a war memorial to the veterans of Putnam County, Indiana, dedicated in 1947. Today, it's on display at that outdoor memorial in the town of Greencastle. Deidre of Wandering Goblin visited it recently and took some excellent pictures, including the one above.
