Major Jackson "Dipper" Spencer is the CAG aboard Galactica just before her scheduled decommissioning and conversion into a museum. He is a liked and respected officer who mixes easily with his pilots. Off-duty he enjoys joining his pilots in a card game, while on-duty he takes his work very seriously and treats his pilots with a firm but fair hand.

Decommissioning Galactica

In the final days of Galactica's decommissioning preparations, Spencer enjoys a cigar while playing a game of triad with Colonel Saul Tigh and Lieutenants Karl Agathon, Kara Thrace, and Sharon Valerii. During the game, Thrace and Tigh trade barbs, with Thrace broaching the topic of Tigh's estranged wife; after Thrace wins the game by having full colors, Tigh flips their table over to assault Thrace and is held back by Spencer before the brawl could escalate, but Tigh orders Thrace be thrown in the brig.

During the decommissioning ceremonies for Galactica, Spencer plays second fiddle to Captain Lee Adama, allowing the younger man to fly the newly-restored Viper Mark II N7242C—the vehicle flown by Lee's father, then-Lieutenant William Adama during the First Cylon War.

Following the decommissioning ceremony, Spencer leads his squadron—the last fully-operational squadron on Galactica with Viper Mark VIIs—to Caprica, presumably for later reassignment within the Colonial Fleet. While en route, the Cylons launch their surprise attack on the Twelve Colonies.

At the dawn of the Fall of the Twelve Colonies, Spencer leads his Viper Mark VII squadron, rendered impotent by the compromised Command Navigation Program software update, to their deaths (TRS: "Miniseries, Night 1").

Alerted to the attack by Galactica, Spencer locates two Cylon Raider fighters and, after ordering the accompanying Raptor 312 reconnaissance vehicle away from the combat zone, orders his squadron to weapons free to intercept and destroy the Raiders. As the targets approach, all Vipers in Spencer's squadron suffer simultaneous and complete system failures as the Cylons infiltrate their onboard computers using the backdoor programming of the Command Navigation Program upgrade.

The impotent squadron is quickly destroyed by missiles deployed by the two Raiders, with Spencer among the first to be killed (TRS: "Miniseries").

Thrace later recites his callsign along with other fallen pilots in her dedication during a toast celebrating the death of the ace Cylon Raider, Scar, by Louanne "Kat" Katraine (TRS: "Scar").



  • In their DVD commentary of the Miniseries, producers Ron Moore, David Eick and director Michael Rymer note they were very impressed with actor John Mann's performance as Major Spencer. They were disappointed in killing off his character, jokingly wishing to bring him back as his character's "twin brother" because they enjoyed working with him so much. Mann eventually returned for "Black Market," but all his character's scenes were cut from the episode.
