A slight bit of progress:

I can add the WM_CLASS property with xprop:

xprop -name FlightGear -f WM_CLASS 8s -set WM_CLASS FlightGear

And then restart openbox:

openbox --restart

and the flightgear window loses its decorations and everything - except 
that it doesn't move.  Here's the pertinent section from the rc.xml file:

  <application name="FlightGear">
          <decor>no</decor>
          <shade>no</shade>
          <position force="yes">
                  <x>center</x>
                  <y>140</y>
                  <monitor>1</monitor>
          </position>
          <focus>yes</focus>
          <desktop>1</desktop>
          <layer>above</layer>
          <iconic>no</iconic>
          <skip_pager>no</skip_pager>
          <skip_taskbar>no</skip_taskbar>
          <fullscreen>no</fullscreen>
          <maximized>false</maximized>
  </application>

Everything happens except for moving the window.  It loses its 
decorations, moves on top, gets focus - and stays right where it is.  
It's like the position thing is being ignored.
