A fully mended Richard Hammond returns to following his terrifying 288mph crash. The presenters set out on an epic road trip of the USA braving the heat, flies and some very angry locals along the way. Richard and James make one small stumble for man as they attempt to launch a Robin Reliant into orbit, the boys go all rural as they grow some bio-fuel with the some big tractors, and they build stretched limos to chauffeur some stars to the Brit Awards.
