Not necessarily related to the OP’s Sonic, but if you want to see how a little Z pull can cause a frontal collapse have a look at the end of the Flysurfer YouTube vid for inflation and launching the Flare Moustache……. Just general info but a lovely clip of wing behaviour!

Yeah I noted that. Why does it do that? Low wing loading plus increased pitching moment due to increased camber?

I was thinking the same. If you give the wing more camber the LE can tuck under into a luff if it is well forward. I have seen this particularly on my Montana.
