Not sure when this was moved from Roumours and News so I can't say whether you posted it whilst in R&N, however in case you weren't sure, PS1 is an advanced 747-400 computer based training aid, initially designed for Lufthansa's 744 crews to use whilst at home.
Whilst it is on computer, it is certainly not a game and basically if you don't know anything about how 747s work then you don't have much hope of running the program successfully as you need a knowledge of most switches just to fly the thing!
I hope pilots all over the world will find my utility useful if they have windows 2000 installed on their computer, I personally know a few who will benefit enormously from my work.
