When you're in the tower, you can look around using the hat switch the same as when your in a plane. You can also set the head position in the same way but between towers the orientation seems to change.
Eg. At one base i set my head position to be all the way to the left and save (f10).
Then if i change fields my head might be all the way to the back, front or right depending on the orientation of the field.
Shouldnt it remember this relative to the building's orientation?
