I am very grateful to Czech climber Klára Kolouchová, who invited me to join her at U.S. International expedition to the second highest peak of the World, mystic K2 at Karakoram, Pakistan! This is a short movie about flying a drone at high altitude at Camp I (6334 m a.s.l.). Full documentary movie will come soon. You can check our expedition at: http://www.klarakolouchova.cz
This is film by Petr Jan Juračka, 2016. You are welcome to check my webpage: at http://www.juracka.eu, as well as my page at Facebook: http://www.facebook.com/petrjanjuracka and Instagram: http://www.instagram.com/petrjanjuracka.
UPDATE ABOUT THE RECORD:
After publishing this video I am receiving links to interesting to great drone videos at high altitude. Great polish film maker David Kaszlikowski sent me this unique footage of David Lama and Corey Rich: https://www.youtube.com/watch?v=Qchy7BVid9Q. It made a bit sad, as I was going to delete my record from the title. BUT! When checking flying log I found, that my take-off altitude was 3664 m a.s.l., what I can confirm when checking the satellite image. So, I am still not aware of any other higher flight of another commercial and civil drone :-) However, there are more higher flight with custom build drones, i.e., by awesome John Griffith who flew at 6500 this spring.
