Landing Signal Officer
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
The Landing Signal Officer (LSO) is the officer who is responsible for all flight operations on the flight pods of battlestars and other military vessels. This includes the landing of all vessels, from Vipers and Raptors to small liners such as Colonial One, as well as the operation of the launch tubes (Miniseries, "Final Cut", "Flight of the Phoenix").
Up until his relief from duty and confinement to quarters for waging a private bomb campaign against Baltar's defense counsels (first Alan Hughes, then Romo Lampkin, in "The Son also Rises"), Captain Aaron Kelly was Galactica LSO. Kelly's replacement in the position has not yet been featured.
