Not today but last thursday and in real life:
I had the possibility to get a sightseeing flight inside a glider (Alexander Schleicher ASK-21) during my holiday in Sauerland in Germany. We took off from Meschede-Schüren Airport (EDKM). Later the pilot made with me agreeing two loopings and got close to 4G during it (probably they expected me to vomit cause I got plastic bag before flight, but didn't needed it) and also some zero G maneuvers, this was short before landing and wasn't able to film it. During the take-off we got dragged by a Robin DR-400-180. I also helped at the airport to get other gliders in the air.
I really enjoyed the flight and got me thinking to join a glider club. And I probably will try to do it soon, not in Germany but in the Netherlands.
