You can place static cameras from the mission builder, then you can cycle them with ctrl+F2 (same key used for enemy aircraft) or from the drop down menu (enable mouse cursor with F10, right click and select from the menu).
As for the previous comments, i agree with the "being in a movie" feeling. Yesterday i fired up the stock bomber intercept mission from the QMB and was shooting up some Blenheims in a 109E4 to test the new cannon shells, i got greedy and their gunners got some good shots at me. Wounded and with both radiators busted i made an emergency dive out of the fight and landed at the nearest friendly airfield with 3 kills confirmed.
I taxied away from the runway, switched off my engine, opened the canopy and then i suddenly heard "vvvvvvvrrrRRRRRRRROOOOOOOooommmmmmm" as the wingman is banking overhead
More than anything else, it's the sound of aircraft from afar and when they fly over you when you are on the ground that has impressed me the most in terms of the new sounds.
