Tenez, un type a fait un petit calcul sympa sur le forum officiel...

I just want to mention that all of you are insane!
This is almost impossible mission.
Any one here that want one aircraft need to spend ~8+ hours every day in that game.
125 wins = ~250 games to play (probably more).
1 game take about 12 minutes => 250 * 12min = 50 hours of gameplay
Every day you will need more than 7.14 hours of gameplay to win one aircraft.
