C’est moi celebrating the 50th Anniversary of my solo flight in the back of a L-13 Blanik glider at the Deep River Ontario with Dave Beeching from the Deep River gliding club.  We were up for about 18-20 minutes before a fast developing lightening storm cut the flight short — but I bet the thermal activity within the CB build-ups would have been spectacular  ;~)

Gracias,

Bob.
