In regards to Kweassas post, newbs, vets, and being good at anything.
Getting good at anything means that basicly you are going to have to make some mistakes. In this game, mistakes usually end with death. The way I always looked at it was, you're NOT REALLY DYING. So if you do "DIE" in your plane, think about what it was that got you dead, and try to fix it. There is always something to take away from every fight, or things. Lessons in AH are only learned through making mistakes and getting blown out of the sky.
To put it at bluntly as humanly possible, if you are going to fly like a panzy, never die, and always be afraid to commit to a fight that you might die in, then you WILL NEVER GET BETTER.
