During the escape from the island by 2nd Mate Johansen and the other sailor (the only two surviving crew), Johansen is seen piloting the vessel, using throttles such as are only used on boats with a bell system, with the vessel responding immediately to the changes he makes in the wheelhouse. However, a bell system necessitates that another person manually throttle the engines from below decks, responding to chimes triggered by the throttles in the wheelhouse. Despite this, both survivors are seen in the wheelhouse at the same time during these changes, and it is indicated that only Johansen and (the corpse of) the other crew member were recovered from the ship.
