Once a futuristic idea confined to the sketch books, unmanned aerial vehicles, more commonly known as drones, are becoming a frequent sight in picturesque environments as photographers and videographers strive for the perfect shot. In this series, Tony Robinson dispatches drones across Britain to reveal places and areas where there is no public access and can only be reached from the sky. Sites include an abandoned theme park, a flower farm in full bloom, top-secret Cold War bunkers and much more.
