From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Killian is a Viper pilot.
He is the sole Viper escort for the shuttle carrying the Arcta expedition. After being detected by a group of three Cylon Raiders, he heads them off, destroying one. However, he strays into the firing range of the Ravishol pulsar and is subsequently destroyed (The Gun on Ice Planet Zero, Part I).
