The story of John C. Houbolt, an unsung hero of Apollo 11 and the man who showed NASA how to put America on the moon. Without John C. Houbolt, a mid-level engineer at NASA, Apollo 11 would never have made it to the moon.Top NASA engineers on the project, including Werner Von Braun, strongly advocated for a single, huge spacecraft to travel to the moon, land, and return to Earth. It's the scenario used in 1950s cartoons and horror movies about traveling to outer space.
