Well, thanks again ! I'm feeling like a star .

Reassuring too, because you got almost exactly what I wanted to convey. The only difference : the two in the bottom right were supposed to be about learning to fly (fly properly and take-off).
Excellent suggestion! You're absolutely right. I'm gonna correct those forts. Don't hesitate if you have other ideas or suggestions!

And thanks for the vote of confidence. Pretty sure yours will be in the race as well .
