I have seen an ASW20 where the wings departed the fuselage together-

As a Schleicher driver I'm interested to know what failed. How did
the wings separate from the fuselage but remain together? Did all the
lift pins fail, or did the lift pin sockets in the wing roots fail, or
was there somehow sufficient bending of the spar that the lift pins
detached without the pins or sockets failing. Maybe the whole lift
pin carry through structure detached from the fuselage but isn't it
attached to the landing gear?

I'd always assumed the spar would break before any of that could
happen but I know the 20 spar is more flexible than some.
