Hi Major!
You will not be flying alone (unless you're on a recce run or something
); you'll have your wingman, your flight, and the whole squadron to go with you. And yes, we'll have other supporting (and non-supporting, i.e. random) flights present in the mission as well.
Re: Pause, well, you can do almost everything while paused, the only thing you won't be able to do is to fire your guns!
So you can take your time, zoom around and take screenshots of all the destruction you've caused and turn them into works of art!
