The Flying Wallendas are the most famous high-wire circus act of all time. Founded by their demanding patriarch Karl Wallenda, the family has been performing for close to a hundred years as of this posting. In the process, they have experienced great triumphs as well as great tragedy, including the infamous fatal collapse of their seven-person pyramid in 1962 which this documentary recounts. (Unfortunately, this copy of the documentary ends before telling the story of Karl's fatal fall in 1978 when he was performing in San Juan, Puerto RIco.)
