The arrival roster at Deep Space 9 listing the Oregon
The SS Oregon was a starship that was registered for Federation travel in the late 24th century.
Under the command of Captain W. Clinton, this vessel visited Dytallix in 2370. From there, it was due to arrive at Deep Space 9 on stardate 47567.2. (DS9: "Whispers")
The Oregon was never mentioned or shown, it was simply listed in an okudagram graphic of an arrival roster on a viewscreen. The graphic was also populated by some other in-jokes.
