The rear occupant would have walked away
I didn't see those picies.
Still for a glider which would no doubt have stability issues after the canopy popped, without the gear and flaps oh, and NO PILOT its a pretty tidy mess! Not far off the van that over/undershot Beagle bay (which was a walk away). I know it goes against SOP but would have been interesting to see the result had they had gear, flaps structurally sound and a pilot.
