Big Blue Sky is a feature length documentary about hang gliding, the first Extreme Sport, and how it started. Big Blue Sky is the story of the ”Lost Frontier“ of flight, tracing the origins of hang gliding from the 1880s thru today, focusing on the golden years of this exciting sport, the 1970s. It is a story of mankind’s spirit, dreams and experiences as much as it is a definitive historical reference. Sorry we cannot ship this DVD overseas at this time but it is in the works. Formatted for North America only.
