Concise and entertaining documentary about trials, tribulations and successes of hardworking engineers at SpaceX led by Elon Musk. Real puts into perspective the gravity of responsibility all the team members carry behind the scene when the flight has people on board. The documentary filled in all the historic events that lead up to a low point in American space flight and subsequent policies to privatize important space programs. It's a well made documentary that hit the important things. Definitely inspiring stuff for space enthusiasts like me.
