Watch On the Threshold of Space

Captain Hollenbeck (Guy Madison), is a veteran pilot who has experienced the worst of the Allied invasion missions in WWII. He is now a prime candidate to lead the tests at the new space exploration bases of the most secret agencies. This is a professional soldier, pilot, patriot, and icon to champion the early missions of the US space exploration projects. The battle-tested readiness of this man will set the standard for future missions to parts unknown.
