From MarcsHomepage
End of 2021 I started flying real airplanes, not only simulated ones.
Somewhat later, I found out that flying gliders in a club is not my cup of tea and I switched to flying something, where an unpowered landing is considered an emergency.
I managed to obtain my sports pilot license end of April 2025.

There are a couple of useful tools for gliding.
All of them are web based, work cross-platform, or have at least a Linux version available.
