Continuity: When the EEV report is being made at the beginning of the film, Ripley is listed as "LT." - lieutenant. Yet, Ripley's rank was always a warrant officer, a lower rank than lieutenant (the extended inquest of the Director's Cut makes this clear). While it's true that Burke promised her that she'd be reinstated as a flight officer, since they never returned to Earth it is unlikely that this occurred, and certainly not at a higher rank than she was prior to her return to LV-426.
