The Warden Kelvin.
The Warden Kelvin was a transfer boat used in 1963 as transport to and from Alcatraz. It was used by Emerson Hauser and the lead officer to transfer a prisoner on the 20th of March, 1963, only to find the prison deserted.
Perhaps only a coincidence, but the name Kelvin was displayed on a billboard during the pilot episode. Also, Harry Kelvin is the name of JJ Abram's grandfather, and was the name of Federation Starship commanded by the father of Captain James Kirk at the time of this death in Abram's reboot of Star Trek.
