"The analysis team, which went over the lifeboat centimeter by centimeter, found no physical evidence of the creature you describe." "Good! That's because I blew it out of the goddamn air lock! Like I said..."
Van Leuwen headed up the executive board that interviewed Ripley aboard Gateway Station in 2179 in order to ascertain what had caused her to destroy the Nostromo by self-destruct. After hearing Ripley's testimony for several hours, and despite acknowledging that the Nostromo had indeed set down on LV-426, Van Leuwen ultimately dismissed her claims that a hostile organism had been responsible for her actions, primarily citing the fact that no trace of the creature could be found anywhere on the shuttlecraft Narcissus. Despite the huge loss of investment the destruction of the Nostromo represented, he decided not to press criminal charges against Ripley. However, owing to her erratic behavior during the tribunal, he revoked her flight status and committed her to several months of psychiatric evaluations.
Following the tribunal, Van Leuwen casually explained to Ripley that another reason he had rejected her claims was that the colony of Hadley's Hope had been set up on LV-426 for more than twenty years and the people there had never discovered anything like the creature Ripley described.
