Recollections: I got checked out in the G103 while working with the FAA in Wichita, KS.  To me (having come out of various Schweizer gliders) it was a real step up in performance.  Compared to the modern gliders, I understand its performance is not considered very good, but I always liked the way it handled, it was roomy and just a solid glider. Unfortunately, my dream of flying out at McMasters a ton ran into the realities of life so I only flew this fine aircraft 4 times (in Wichita). While scanning some photos, and checking my logbook, I found pictures of me flying the G103 on a TPS class field trip, see photos below.

My actual first flight in type in September of 1986

Grob 103 post-flight “Hero shot”. Remember: never take the hero shot BEFORE the flight, only AFTER (otherwise the plane will break).
