I’ve seen a few of his videos.
He made a big deal about the arched bands of steel installed under each wingtip, claiming they’d probably save the plane in the event of a groundloop.
Looks like they didn’t work as he’d hoped.
But he didn't ground loop. He got blown over by a severe crosswind while taking off.
It wasn’t a ground loop, and Patey himself didn’t call it that.
The plane was off the ground and was caught by a wind gust when the left wing was up. Patey described it like being a kite, and having no control.

Wingtip skids are nothing new.
They were common on aircraft dating to World War One and earlier. Look up some images of the Fokker Triplane at Old Rhinebeck Aerodrome: it had wooden skids (not sure if that’s still true). They looked like axe handles.
A number of aircraft of the period were equipped with bow skids, to reduce the chance of nose-overs, which can happen on landing in aircraft with taildragger undercarriage. Nose-overs could also occur on takeoff if the field was too rough, or the machine hit a pothole. Paved runways did not exist.
