That is strange that you couldn't get the cam to face forward. Once you hit the forward thrust (left mouse) while above an altitude of 300 the camera should follow and rotate with the player. The mouse-look camera is only at low altitudes, for take-off and landing.
It was something that I was working on right up to the deadline so I'm sure there are bugs and exceptions.
Maybe a better way would be to always have the cam rotate with the player and face forward, but have OPTION of mouse-look, which can be toggled on and off.
