Destination Moon (1950)

A team composed of an aerospace scientist, an ex-Air Force general, and an industrialist conceives an ambitious plan to land Americans on the moon. From their base in the Mojave Desert, they construct and successfully launch a spacecraft named "Luna" that contains a cargo of four astronauts. But a critical miscalculation of needed power to escape the moon's gravitational pull may put the astronauts' lives in danger.
