Factual error: The movie takes place in 1968, and Frank Beardsley is supposedly developing the Fresnel Lens Optical Landing System (FLOLS) for aircraft carriers. The system actually was developed by the British and was installed on US carriers starting in 1955.

Factual error: At the start of the movie, Frank is shown departing the Enterprise along with enlisted men. On large ships such as carriers, there are two separate brows (i.e., "gangplanks"), one for officers and one for enlisted personnel.
