Welcome!
Try not to get discouraged, you are going to die, A LOT. Sometimes by enemy gunfire, sometimes by colliding into things, by losing control of the plane, by trying to land, but if you stick with it the community here is great and most are willing to give you a hand if you ask.
Try all the planes out, they all have very unique flying characteristics. Some are easier to learn on than others.
When you find one you like, stick with it! If you have a WWII favorite that is listed in game that's a big plus.
Overall, have fun and see you in the air
