A lieutenant who takes the helm of the Enterprise while Sulu is on a landing party, and is at her post when the ship is hurled nearly a thousand light years across space.
Lieutenant Rahda is a helm officer aboard the Enterprise in the third-season Original Series episode That Which Survives. She was played by Naomi Pollack.
With Sulu on the surface of an unexplained planet alongside Kirk, McCoy and D'Amato, Rahda mans the helm under Spock's command. After a powerful jolt she reports that the planet has vanished and then notices that the stars are in the wrong positions; Spock calculates that the ship has been displaced by 990.7 light years.
Rahda takes the ship back at high warp. When sabotage by the apparition Losira causes the engines to run away, she calls out the rising speed as Scotty works in a crawlway to shut down the matter-antimatter flow, and she brings the ship into orbit once the danger has passed.
