If everyone flew to not die putting forth zero risk(irony in itself), it would be a constant tug o war match to get the upper hand in fights. Everyone would be flying at 30k in hordes playing cat and mouse with other hordes. That's why.
No, because the call of the kill and aggression and testosterone more than balances out any concern for a cartoon death. It requires immense restraint to *not* go in fangs-out hair afire against every bandit.
EDIT: My attitude is not the one that led to a big bite of my own foot by calling someone who made a living landing jet fighters on a boat "timid"....that says something IMHO.
FURTHER EDIT: Are you guys really THAT pissed off when someone bugs out? Because, let me tell you, when someone does it to me I generally know why they were going to do it...I was about to shoot large chunks away from their airplane. Doesn't make me mad enough to throw my headset across the room or anything.
