It's amazing how calm pilots can sound when under pressure. I once listened to a recording of a Skyraider pilot in the middle of an engagement with a group of 3-5 MiGs, and the only time he ever really sounded excited was I think when he had like the entire flight right on his six, and even then he was still using his 'indoor' voice
I'll have to see if I can dig that recording up again, someone posted it on the Il-2 forums a long while back. It was pretty neat to listen to.
