Gallaudet DB-1

The Gallaudet DB-1 was a United States day bomber prototype designed during World War I. Two protoypes of the aircraft were constructed, however testing revealed flight control issues and serious structural problems with the wings. The aircraft was known to be extremely heavy, which turned out to be more than a ton over the weight it was designed to be. The aircraft never got off the ground. The National Museum of the US Air Force states that "the DB-1, although unsuccessful, was quite advanced for its time." The aircraft was succeeded by the Gallaudet DB-1B, which was lighter, but the flight characteristics were still poor.
