Here’s Patey describing the accident; https://www.youtube.com/watch?v=NfctWAoDXvs

[Ex gun maker.]

I watched the video.
One wing was already high even before he began rolling.
Very soon he’s on one wheel and already in trouble.
I would not call that a “Ground loop”, more like he spun out.
Once he left the tarmac and the gear his soft dirt there was no hope.
