This theory doesn't work though.  Think about it: in cockpit mode, the
orientation of the aircraft is "bolted" to the FDM orientation.  If
the FDM points left, the cockpit will point left by the same amount.
Jitter from the FDM would cause the *scenery* to jitter, not the
cockpit.

Conversely, in tower view, the scenery should stay put while the
aircraft jitters.  But it doesn't, the aircraft geometry jitters here
too.  So the problem somewhere in the model's scene graph; there
really aren't any other places it could hide that I can think of.

Could you give us a quick rundown of exactly which matrices or
ssgTransforms get added to the scene graph and where they come from?
I started tracing this out but got distracted by the glut font stuff
(different discussion entirely). :)
