When Sam Carter is introduced to the team going to Abydos, Kowalski is trying to scare her (or prove how cool he is?) by explaining how difficult the trip through the stargate will be. He asks her if she has ever pulled out of a simulated bombing run in a F-16.
Why does he explicitly say "simulated"? Since the tone of the show is otherwise very much "kill the bad guys" I can't imagine that it's to prevent us from thinking that these characters have never been to war, so why not just ask about a "bombing run"?
