It's amazing to watch this, I would like to start with that. Even watching recordings for decades ago, I become emotional wi5 every shuttle launch. Having owned and watched all the documentaries released on all the Apollo missions, I was excited for this. However, in the first episode in giving us a background on the development of the program and Astronauts , it was sad, disappointing and surprising that the Enterprise was not mentioned or shown. That was the first test of the shuttle and landing, while it did not launch and was carried up to glide down, it was an important and historically significant part of the amazing Space Shuttle Program.
