This was an enjoyable thread to read.
I guess I had a lot of problems with this question for a while. But people here have summed up why the answer is clear to me now.
AH is not a sim. It's a game.
Because it's not a sim, everyone has fun playing it as the like - some rtb, while others crash the plane into the ground on purpose.
Anyone who does auger like this must have a clear mind about AH being a game - you play by the rules of the game and that's it. What's funny is when people fly this way, then advocate AH as some "serious sim". If it was, there would be a huge penalty for intentional augering. Heck - even damaging equipment for no reason should get you a court-martial.
The problem is when someone wants to think about AH as more than a game. When you do this, it's easy to get confused really quickly - not just from the auger standpoint, but from many other aspects as well.
Personally, I find that flying the Falcon 4 campaign, coop with squaddies, a lot more satisfying "as a sim", since it is mission-based by nature, has no labels, is on a realistic map, has two "sides" in the war, etc. etc. Even ejecting out of an undamaged plane for no reason can get you busted!
AH could be a more faitful from a sim standpoint, but it's not because people in general don't want it that way (myself excluded).
