This documentary, directed by David Fairhead, offers the viewer a most candid behind the scenes look at Houston's Mission Control Center during the early U.S. space program. If focuses primarily on the Apollo Program, of the 1960's and 70's, with plenty of archival footage of the times and interviews with those that manned the control room, as well as the astronauts that flew the early missions.
The film includes the tragedy of Apollo 1 when 3 astronauts died in a capsule fire as they awaited liftoff at Cape Kennedy, the first manned orbit around the moon on Apollo 8, and, of course, the remarkable team effort to return Apollo 13 safely back to earth after a life threatening malfunction (you may have seen the movie).
Naturally, I'm not forgetting Apollo 11, where Neil Armstrong became the first man to set foot on the moon, setting off shock waves and awe around the world. It was fascinating for me, even though I have seen other movies on this subject over the years, to hear the intricate details of what went into each flight from the engineers, flight controllers, and astronauts that lived through every minute of it.
