Battlestar Galactica, Tyrol's Thrust Governor Relays

original movie prop

These are Tyrol's thrust governor relays used on the Raptor ships. This particular set is from Season 4, Episode 4 'Escape Velocity'. In the episode, Tyrol is distracted while working on the the ship and forget to replace the burned out relay. When Racetrack takes the Raptor out, it malfunctions and she has to return for an emergency crash landing. Tyrol pulls the good relay out of his pocket and, with a slight look of horror, pulls the bad one out of the ship. These are custom made props with machined aluminum ends. The internal parts are actually read/write heads out of a computer hard drive...
