In 2267, Hansen was on duty when the Enterprise traversed an ion storm. He reported force five vibrations when the ship's log apparently recorded the death of records officer Ben Finney. He remained aboard as part of the command crew when Kirk's court martial reconvened aboard the bridge, and he piloted the ship back to a stable orbit following a loss of power orchestrated by Finney. (TOS episode: "Court Martial")
Hansen was in operational command when Spock transmitted false orders from Starbase 11 for the Enterprise to depart on a top secret assignment and locked navigation. Spock returned command to Hansen when surrendering for mutiny, and he was at the helm when the ship arrived at Talos IV. (TOS episode: "The Menagerie")
Kirk allowed Perithees Ambassador Sork to take Hansen's place at the helm briefly, just prior to the ship's discovery of a mysterious unmanned vessel. Hansen retook control for the Enterprise's approach and investigation. When the vessel suddenly took off, with a landing party and Sork aboard, Hansen brought the ship to outer orbit of Romulan-controlled Tekton, operating a mass-nullifier to mask their presence.

In 2268, Hansen manned the helm with John Stiles at navigation and Ensign Jana Haines at the sciences station during the ship's silent-run approach to the Libros system and the sensor-scrambled landing of Galileo on Usilde. (TOS - Legacies novel: Best Defense)
