How does one land upside down following a PT3?

According to article: Released 100-200 feet AGL. Minor injuries to pilot.

The photo show tail boom broken behind wings. Tail and wings and nose appear intact. Speculations on how the pilot landed like this?

High energy ground loop?

Mainly winch at the Myndd.
Wing drop at start of winch launch- glider cartwheeled? Spun off failed
launch? Turning low off failed launch - wing clipped ground - glider went
inverted? Who knows -but it time the accident report will tell us.

Speculation that winch launch commenced with elevator not connected.

If the CG is within the allowable range, most gliders with a CG hook actually perform a fairly decent winch launch w/o elevator input.
We don't have any real info so everything about this accident is pure speculation.

Which would perhaps lead to a steep climb, stall/spin and rotation in a near vertical attitude resulting in an inverted impact, usually fatal. Happened on auto launch in Georgia several years ago with an all-flying tail stall on a Phoebus C. Pilot hurt but survived.

Recognized hazard in winch launching whatever the cause. Like all accidents, preventable.

It's super simple ... you land on your roof .... geez

But how do one land inverted without breaking wings, nose, or tail AND walk away?

I'm more interested in well-dissected historical cases where this has happened, than in this particular undocumented accident.

This is a serious question then?

It's not possible to "land" (i.e. in a controlled fashion) a glider inverted. Wing incidence, camber and dihedral are all against you. If you were to try this, the glider would touch down on the tail with the nose pitched rather high and the fuselage would drop hard on the cockpit, still with significant forward speed. It's a call-911 event. And there probably won't be any need to hurry.

When someone crawls out of a wreck that stops inverted, it's because the glider flopped on its back at the end of some sort of tumble and it happened to do so in a relatively gentle fashion. It's not a high percentage play.

Then maybe the fuselage would break behind the wings, thus dissipating a great deal of energy and the pieces would come to rest relatively intact like in the photo of the Long Mynd landing. I conclude that 'flying the glider' until it stops is the better option even if the glider is inverted.

Tumbling a glider in 'a relatively gentle fashion' is a possibility??

Related: Does anyone know of a case where a glider was flipped inverted on turn to final in rotor-in-pattern conditions? I'm curious because I got thrashed severely on turn to final a few weeks ago.
