If it's the same video, they've got a pretty impressive glider fleet and utilisation ....whether the social aspect can rival or surpass that of the GSA is probably an entirely different matter however.
A quick trawl shows some still shots of cadets in "fearless glider pilot " pose...but that's marketing for you.
However, the same video also says, twelve flights to solo....now, even with aero tow, that's a bit quick...and notably, not a winch in sight, but, even more intriguing, according to the video, was, that, after one Semester, you could become an instructor....for mere mortals, this takes a few years of hours building / badge gaining, and.....experience.
