Executive Producer Tom Hanks assembled a true all star cast for this series covering the American manned space program from inception through the last visit to the moon.
Rather than take a strictly chronological approach FTETTM branches off periodically. Episodes covering topics like the development of the lunar lander and a look at how life on Earth was for astronauts wives overlap the main story arc, but are given separate episodes so that their stories can be shown with the importance they deserve rather than shoehorned in to other episodes as a side story.
If you remember some of these events you will appreciate this faithful retelling of the story. If you are not familiar with this portion of history, this is and excellent introduction that may leave you wanting to learn more about space exploration.
