A Starfleet ensign who takes the conn of the Enterprise-D on several occasions, including the missing day of Clues and the dangerous passage through a dark matter nebula.
Ensign McKnight is a flight controller aboard the USS Enterprise-D, played by Pamela Winslow in three episodes of The Next Generation.
She is first seen at the conn in the fourth-season episode Clues, in which the crew slowly realise that they have lost a whole day rather than thirty seconds. She returns in In Theory, where the ship explores a dark matter nebula whose distortions open gaps in the hull and deck; Picard ends up piloting a shuttle ahead of the Enterprise to guide her course out.
McKnight makes a final appearance in the sixth-season episode Face of the Enemy. She is one of a group of recurring relief officers who filled the conn position in the years after Wesley Crusher's departure.
