lightning stikes a ASK21

There is an article in this month of "Business & Commercial Aviation"
regarding lightning.

It says that in 1999, a ASK21 desintegrated large sections of the
fuselage, while flying in clear air, about 800 yards from a cloud.
Both pilots were ejected from the strike, but fortunately were wearing
parachutes.

The same article goes on to say fiberglass, especially carbon fiber is
conductive. So if you are on the ground and a thunderstorm is over the
airport, to seek shelter inside a building and NOT inside the glider
which has no protection.

Has nayone heard this before? Do you know someone who had a lightning
strike in a glider before?
I am just curious as I never heard of this before.
