Counselor Deanna Troi (Marina Sirtis) has always been scapegoated for crashing the USS Enterprise-D in Star Trek Generations, but the truth is that she was never to blame for the crash. Troi served as ship's counselor on the Enterprise-D for all seven seasons of Star Trek: The Next Generation, but worked in later seasons to expand her role on the ship, obtaining a promotion to commander after passing the Bridge Officers Test in TNG season 7, episode 16, "Thine Own Self". This new rank included shifts overseeing the bridge as part of her duties, which meant she was present on the bridge more often and occasionally piloted the ship as well.
Unfortunately for Troi, her most memorable time piloting the Enterprise-D ended in disaster. Toward the end of Star Trek Generations, the ship had to separate the saucer section in order to save the crew from a warp core breach. This maneuver was successful, but just as Troi took the helm and was about to engage impulse engines, the shockwave from the exploding warp core disabled the saucer and pushed it into the atmosphere of Veridian III. Troi was forced to pilot the ship into a crash landing on the planet, completing the Enterprise-D's total destruction since the saucer was irretrievable after the crash.
