The Philadelphia Experiment

This interesting sci-fi adventure (named and adapted from a widely-reported incident in 1942 about a battleship that supposedly disappeared with all its crew) begins in 1943 on a naval destroyer where strange experiments are being enacted. Something goes wrong and the ship and two crewmen are sent forty nine years into the future. They then try to solve the mystery of how they got there and how they can get home. In the meantime, one of the soldiers falls in love.
