While on a mission to the planet Minos in 2364, he came at odds with Lieutenant junior grade Geordi La Forge when the latter was placed in charge of the Enterprise-D by Captain Jean-Luc Picard. The Enterprise came under fire from a Minosian weapon in orbit of Minos, and Logan insisted that La Forge give him command due to his superior rank and experience. Instead, La Forge ordered him back to main engineering. When La Forge decided to do a saucer separation and battle the enemy only with the stardrive section, he placed Logan in command of the saucer section and gave him the order to retreat to Starbase 103.

Background information Edit
Logan was played by actor Vyto Ruginis.
He appeared to have replaced Lieutenant Commander Argyle as chief engineer. However, Commander William T. Riker's line in TNG: "Where No One Has Gone Before" that engineering matters were overseen by "one of our chief engineers, in this case, [Mr.] Argyle" seems to imply that the ship had more than one chief engineering officer at the time. Therefore, it is possible that Sarah MacDougal, Argyle, and Logan all served as chief engineer simultaneously. This practice of having more than one chief engineer seems to have come to an end by 2365, when Geordi La Forge became the sole chief engineer of the Enterprise-D.
