Spaceways (1953 film)

Spaceways is a 1953 British Science Fiction film set primarily on a space station with a murder mystery.

Plot
Engineer Dr. Stephen Mitchell is part of a British space program that are planning to launch a satellite that will permanently orbit around the Earth. At a cocktail party with him and his colleagues, it is announced that the project has been approved by the defense council. But his wife Vanessa is not enthusiastic about the project nor living at the high security base. She sneaks away with Dr. Philip Crenshaw, who she is having an affair with, while Stephen leaves with Lisa Frank, a mathematician on the project who is in love with him. When Stephen returns home, he has an argument with Vanessa, with Stephen secretly aware of her kissing Crenshaw.

Meanwhile, the rocket soon launches, but it does not reach maximum height. It is soon discovered that Crenshaw and Vanessa have disappeared. Soon after, Dr. Smith secretly investigates around the base, coming to the conclusion that not only were the two murdered by Mitchell, but they were hidden in the fuel tanks of the rocket to cover his tracks. Smith approaches Mitchell with the accusation while telling him about Crenshaw (who concealed having a degree from Germany) being a spy.

Mitchell comes up with the idea to go in a second rocket into space to try and prove his innocence. Smith discovers that there was a new member on the team prior to the disappearance, and that a guard had died in an accident a week earlier. Soon after, Crenshaw and Vanessa are discovered by Smith and the police at a seaside cottage, with the former planning to go to the east instead of America. However, she is killed in a scuffle between Crenshaw and Smith.

After the launch, Mitchell is surprised to see that Lisa is aboard the ship, having convinced Toby to let her be on the ship instead of him. Despite it being revealed that the bodies are not on the ship, Mitchell and Frank try to disconnect the middle section of the ship, which results in an explosion, making the rocket go out of control. However, Steve releases the fail-safe handle, saving them from destruction.
