James investigates what the Space Race did for all of us who never got a chance to blast off into orbit, discovering that the race to the moon began in Chiswick, West London. James gets to road-test a street-legal version of the lunar buggy, but finds out gravity makes the handling difficult. After taking his own satellite photo from 700km above Earth, he then travels to NASA's launch pad in Florida to see for himself the massive Saturn moon rockets that he once made in kit-form in his bedroom.

James May discovers just how far he can push his body, exploring some of the most remarkable medical advances over the last hundred years. He begins by testing himself in a centrifuge, a machine used to train fighter pilots and astronauts.

James May discovers how, thanks to planes, cars, televisions and computers, our world suddenly got a whole lot smaller. He takes a flight in the pioneering airplane that created the European mini-break and looks at the Ford Cortina - the classic family car that opened up a new world when he was a young lad. James also takes a Model T Ford for a test drive and finds it so difficult he wonders how motoring ever caught on.

James May investigates some of the most ingenious ideas to emerge from 20th century warfare. He flies in the RAFs latest supersonic jet as well as a biplane, getting to grips with just how difficult it was for early aviators to hit their targets. James also joins a group of ex-paratroopers to test camouflage painting techniques. It work so well he cant spot a man just a few hundred feet in front of him, and so turns to a hi-tech infrared camera to spot his enemy.
