Never played MS flight sim, huh?

There are, from random clicker sims to running actual air traffic in flight sims with such realism it took me a while to be certain it was a game (and not a air traffic union or something) when I looked up the website

You can play as an ATC in online flight sims

Colab idea: ATC Sim and the planes are people flying in a flight sim so you talk to real people and instruct them.

I remember there being a fun one on iOS back in the day.
