Our Film

Burkhard Martens, Achim Joos & Charlie Jöst: Thermal Flying

Climbing in thermals is the most beautiful, and also the most challenging part of free flying disciplines. It is a fundamental prerequisite of successful cross country flight. From a pilot’s standpoint, the film shows how to find, core, and efficiently and safely climb the thermal. Four top-ranked pilots, equipped with cameras, will invite the audience into the air. In real situations, they will demonstrate and explain, how to respond to ambient conditions, what to watch for, offer useful tips and tricks acquired by their long-time cross country and competition experience, and describe various alternatives or flight techniques. They will discuss, how to make use of valley winds, how to soar safely, how to locate and efficiently use thermals in the mountains and flatlands, how convergences or magic air arise and how we can use them. Advice for hang gliders is included. On a paraglider, you will be accompanied by a cross country world record holder Burkhard Martens and a winner of cross country world cup Achim Joos. Hang glider pilots are represented by multiple world champion Alex Ploner, flying on flexible wing, and a young talented German pilot Tim Grabowski on rigid wing. The filming took over two years in various flying sites in the Alps, in German flatlands, and also in Spain. General cornerstones of the project were established by Achim Joos according to Thermal Flying bestseller book by Burkhard Martens. Charlie Jöst, a flight cinematographer, contributed with his know-how and precious HD filming equipment. The film is primarily intended for less experienced pilots and paraglider instructors as a teaching aid. However, even expert pilots will find inspiration and useful tips and recommendations for better flight efficiency. Learn from the best, enjoy your flights and safe landings!

The film with original German soundtrack and English subtitles is available as DVD in standard resolution, or as high definition Blu-ray disc..
