With his unique blend of energy and enquiry, James May takes an exhilarating look at the historic moon missions. Four decades ago, James May sat in his family sitting room watching Neil Armstrong and Buzz Aldrin take man's first steps on the moon. Now he dons his space suit and sets off on a one hour orbit around a subject that's remained a fascination. James travels to the America to meet three men who have walked on the moon, to discover how it felt and learn how 1960s technology managed to produce the most incredible machines in aviation history. James also gets his own taste of how it felt to be an Apollo astronaut. He experiences the thrill of weightlessness in the infamous Vomit Comet, feels the bone-crushing G forces of a Saturn V rocket launch and gets to fly to the edge of space in a U2 spy plane - in his own space suit!
