Commander Kelby

Universe :	Prime Timeline
Name :	Commander Kelby [1]
Species :	Humans

An Earth Starfleet officer, Kelby replaced Commander Tucker as Chief Engineer on the NX-01 Enterprise in 2154 when Tucker transferred to Columbia. [1] He was not as experienced as Trip and when Klingon agents sabotaged the NX-01 Trip returned to assist in repairs. Kelby felt frustrated at having Tucker back; when three Orion slave women came aboard Enterprise they used this frustration to encourage him to sabotage the ship. [2] Kelby was suspected of being a supporter of Terra Prime when a shuttlecraft was sabotaged whilst on a mission to fight the organisation's attempt to use the Verteron array on Mars in 2155. In fact he was innocent of the charge. [3]
