You can use F11 to roam anywhere you want and everytime you press it, it will cycle through all air bases. While in the F2 view you can rotate the camera around the aircraft and if you hit ctrl ESC the camera will rotate on that postition. Thats a great way to get some cool angles. ctrl / and * create some cool angles too. Try em all out. You can also get a program that manipulates the default camera angles.
search for LOCFGSetup2-1a on google and read up about it. It may help as well.
