I don’t know of any of you discovered this but if you go to above a certain altitude (I think FL400) there is 0G!
Not a super awesome glitch but quite nice
In the real world, 0G training planes do vertical zig zags to create the 0G environment but in IF, you don’t need to fly a plane on vertical zig zags (like an 2-year old). Just fly at a near the edge of space and you have 0G! If spacecraft and G simulation in cockpits get added, you know how to train for flying a spaceship/spacecraft.
