Back in the mid-1960s, we took a 1-26 over to the Cumberland, MD wave camp one weekend. The wind was fairly strong but I don't recall it swirling around that much. At lunchtime, we turned the glider so the wingtip pointed into the wind and tied it down securely. We were almost at the hut about 50 m away when I heard someone yell. When I spun around, the 1-26 was standing vertically on that wingtip. The swirling wind had picked it up and then laid it down on its back. I suspect the rotor was working that day.
