Like I said Hondo, I'm not using that trick but it is available for others to abuse. Looking back from a fighter towards the bombers will give you a more exact look at where your bullets are respective to the target than you could ever get from the gunner's point of view.
And yeah, a macro that pushes F5, F8, and H gives you instant panoramic view of everything around you with focus as rapid as you can move your mouse.
