I can see how this was inevitable
Some years ago, I disassembled my 2-place Slingsby glider and went home overnight, leaving the wings sitting on some scrap 2x4s laying flat on the grass. These big aluminum wings weighed over 250# each and I never had a worry about them staying right where four of us placed them.
Next morning, they were both piled up against a barb wire fence about 40 feet away. A friend who had camped overnight at the field said he never even heard wind during the night. Fortunately, the only damage was paint scratches.
That left me with a lasting respect for securing anything large that the wind can get to.
