A severe positive ground flash blew a glider apart in
Britain a few years ago.

That was a K-21. The strike entered at one aileron push rod and traveled
to the other aileron push-rod, where it exited, through the spanwise
alloy push-rods and control linkage.

Ohmic heating in the control linkage produced a strong enough pressure
pulse to cut the fuselage in half and to blow out both canopies. The
skins were blown off both wings as well.
