In this programme James May commemorates the 40th anniversary of the Apollo moon landings.
The show saw May interviewing Apollo moonwalkers Harrison Schmitt, Alan Bean, and Charlie Duke, before himself experiencing weightlessness and G-forces similar to that of a Saturn V rocket launch.
As a passenger in a Lockheed U-2 spy plane, May flies to the edge of space where he is able to clearly view the curvature of the earth.
