836 posts and can't take off
Anyways, it's not too hard to get your plane in the air.
To get started, it would be advisable to click on the options tag which is on the clipboard.
Then click preferences and then flight. Check the "Auto take off" box.
Go back to the hanger, from where you can select a plane.
Once selected all you have to do is click on an available runway direction.
You will find yourself in your selected plane with the engine starting up.
Now simply throttle up and up up up you go.
If you don't have a joystick to control your flight I would suggest getting one. The game is much easier to play with one. Although there are some who manage to fly and fight really well with a mouse.
best of luck...
