The A.B. Chambers
The A.B. Chambers was a 19th century steamship in a holodeck program featuring the American author Mark Twain. (LD: "Something Borrowed, Something Green")
In the real world, Mark Twain had piloted the A.B. Chambers in the late 1850s. In 1860, while traveling to St. Louis, the vessel ran aground and sank near the mouth of the Missouri River. [1]
