Very nice indeed. At 1:09 that leading edge is quite sharp for low drag through lowest lateral acceleration of air particles and for high speed and I would not be surprised if the glide ratio is the highest there is between 65 and 70. That slight rake back curve on the outer wing and that small wing-let are perfectly placed. It is fascinating how they get that cantilever wing flexibility and yet it is stiff for twist and flutter. I just wonder how close we are to equalise the glide ratio of an albatross or fly in a helix manner to extract energy out of the wind which helps the albatross cross oceans without flapping its wings, but diving to accelerate and fly close to the water where the wind is slower and then at the right moment circle up to higher altitude where the wind is faster and thus gains energy out of it to dive down again to penetrate the slower moving air , all by flying in a large helix above the sea. We are doing well, but still a little behind nature.

Great vid! Excellent production... thanks!!
wow 0:29 .. looks like there are 10 or more of these super orhids on the ground. Nice place!
Very good video. Thank you for sharing.
