A Starfleet ensign who serves at the conn of the Enterprise-D in 2367, appearing in the fourth-season episodes Final Mission and The Loss.
Ensign Tess Allenby is a flight control officer aboard the Enterprise-D. She appears in two fourth-season episodes, Final Mission and The Loss.
In Final Mission she is at the helm while Riker has the ship tow a radioactive waste barge away from Gamelan V and through an asteroid belt. In The Loss she is flying the ship when it is caught up with a shoal of two-dimensional lifeforms and dragged helplessly towards a cosmic string fragment.
She is one of a number of junior officers who took the conn after Wesley Crusher left for Starfleet Academy and before Ensign Ro Laren joined the crew.
