What happened here? Turbulence? Stall?

Now I could be entirely wrong, and I only watched the collapse, not the rest of the vid. Looks familiar, this little incident that was a good advertisement for a Skyhook.

That came up a while back on DZ.   I know it as the Dubai swoop comp collapse, Dec 2011.  Think it was blamed on turbulence, causing the frontal stall or frontal collapse (negative angle of attack).  Possibly in some way combined with it being on an early non-production version of a Petra, a prototype if you will. But I don't know the details. Search for "JPX Petra - stability issues?" thread.

My guess would be broken riser due to poor maintenance or gear incompatibility.
