In the film, Military Captain Petri argues that the ship should sail in deep water, and have its navigation lights on to avoid a collision. While Civilian Captain Kehding argues that the ship should sail near the cost and keep off the navigation lights. Realistically, these roles should be reversed. Petri's strategies are against military protocol, despite him being a military officer, while Kehding's strategies all apply to military protocol, despite him being a civilian. In real life, the military captain argued that they should follow military protocol, while the civilian captain argued against it.
