The aircraft model used for external views was being included in the height

above terrain check so when the view position and the aircraft model collided
the current altitude kept getting pushed up to compensate, but of course the
aircraft model would get pushed up as well because it tracks the current
aircraft position and orientation.  Thus you had a never ending cycle ...
