George Plimpton is an amateur of many worlds. He has driven a racing car in the Italian Grand Prix. He has even played a bit-part in a John Wayne movie. George Plimpton is familiar to American viewers for his have-ago-at-anything approach. Tonight, Man Alive hands over to Plimpton as he joins 'The Flying Apollos,' a trapeze act with a travelling circus. After 10 days' training, George Plimpton, in a packed big top, himself has a go on the flying trapeze.
