So I was lounging around by the lake enjoying one of those rare warm, blue sky, German Sundays watching my dogs go nuts in the water and fields when I look up above the tree line and see a two swarms of gliders lazilly circling about. It reminded me of discovery channel videos of vultures circling a dead gazelle or zebra and waiting for the lions to finish their meal before diving in on it.

I counted 29 gliders at one point. At least 22 in one thermal alone. My question for you glider pilots out there is how do you avoid hitting each other when seemingly every glider in the sky converges on the same updraft? This sight was something to behold. I understand see and avoid, but the amont of aircraft in such a small space got me wondering how that sight was orchestrated.
