The glider "in" the volcano is a Nimbus 3 DM, D-KTTT. The pilots are Josef Holzapfel and his son. We started from San Martin de los Andes to this pleasant flight.

Kind regards

Stunning! And here's another that was taken on the same flight? If you don't mind, I'll PM the poster with the "real" story.
