Just inches apart formation glider flying...

The quality of this video is just spectacular. Looks like a very
large scale rc glider and a power rc with a camera flying in tight
formation. Many times they are just inches from each other. While
not the real thing (full scale sailplanes with pilots) it is fun to
watch while the snow flies. These kinds of shots would be simply
amazing in real life but just too dangerous to get with any degree of
safety margin. Enjoy.
