Ever crossed your mind not ALL choppers have ejection seats?
Yeah what might the ejection seat be for, how about we have FSX like "You crashed - simulation stopped" message every time you crash, realistic damage modeling would be quite odd in a sim wouldnt it?
Why can we shoot aircraft with our cannons, u arent supposed to do that with this specific aircraft really so no point modeling it in?
I could go on..
ps. If you lose control of a car and it accidentally flies into a river, you think it would blow up / vaporize leaving nothing behind, just because you were not SUPPOSED to "park" it there..? Yeah go tell the driver "what did you think those pedals and wheel are for?"
