In 2012, Danish divers pulled the badly corroded wreckage of a Heinkel He 219 from the waters off the Jutland peninsula, where it had been submerged since World War II. It was a remarkable find: No more than 294 of the night fighters were built for the Luftwaffe, and before this discovery, there was only one known survivor, which is in the collection of the Smithsonian National Air and Space Museum. The Museum's He 219 was one of dozens of enemy aircraft presented to the United States after World War II by U.S. Army Air Forces commander Henry “Hap” Arnold.
