Lovely and informative. The other Hustwit documentaries (Objectified and Urbanised) are a little broader, and less idiosyncratic than this one; but that is part of its charm.
Using recollections and images from all missions, Al Reinert creates an arc from launch to landing to re–entry, and captures the emotions of the astronauts, and not the science. Just a tad epic. The sound track by Brian Eno and collaborators is also epic.
