The Landing Signal Officer (LSO) is the officer who is responsible for all flight operations on the flight decks of battlestars and other military vessels. This includes the landing of all vessels, from Vipers and Raptors, to small liners such as Colonial One and Gemenon Traveler, as well as the operation of the launch tubes (TRS: "Miniseries", "Final Cut", "Flight of the Phoenix").
- Judging from the various duties carried out by Captain Aaron Kelly as LSO, the job in the Colonial Fleet is much more expansive than the title implies. In contemporary U.S. naval aviation, he would be a combined LSO, "shooter" (catapult officer) and "Air Boss" (flight deck operations manager). 
- A slogan on a duty roster in the pilots' ready room aboard the battlestar Galactica, reads "Dominate the ball - Be the ball - There is no life without the LSO" (TRS: "Six of One").

- Borrowed and condensed from real-life advice documented in "Bogeys and Bandits" by Robert Gandt:
- Dominate the Ball!
- BE the Ball!
- You Are Not Alone!
- Trust the LSOs!
- There Is No Life Below the Datums!
