Mine was FS98. I never did a flight on that though.
My first ever PROPER flight was done on FS2004, and it was about two years ago. I remember it clearly. that whole time before, I was just learning about flying. It was in the DeHavilland Comet, and it was a small circuit around Kathmandu. The reason I say Proper, is because it was the first one I used proper procedures.
And by the way Maarten, it's weird that the first screenshot ever made here, is one of the best on the website!
