Wow Lusche. Doubt the new guy much? 
It's a natural thing. People download the game and then just hop into a plane. I did so too. "Oops... Did I do that?"

How many new players can control their plane perfectly before taking off for the first time?
With friendly collisions and kills, you would have to do the real thing: Train new players for extended times before entrusting them a plane for the first time, Set up STRICT rules of engagement, and massively enforce them by a higher hierarchy of players.
Or you can just accept human nature and let killshooter do the work
