The DC-3 was the name of an American airplane used in the 20th century. After Jonathan Archer restored a damaged timeline, a DC-3 could be seen in the time stream as the timeline realigned itself. (ENT: "Storm Front, Part II")
In 2255, a model of this aircraft was on display while being suspended from the ceiling of the Shipyard Bar, in Riverside, Iowa. (Star Trek)
