Here is yet *another* picture of the motion base.  Getting sick of these yet? *grin*
Here you can see the massive steel mount that the hydraulic actuators connect to.  Also visible (barely) are the cushion pads that absorb some of the vibration the motion base can produce.
 

No, your head isn't on wrong, the image IS tilted.  I didn't have much choice since I didn't want to knock the poor old man standing next to me to the floor so I could get a better shot.  I would've asked, but I don't think he could hear very well. :) This is one of the new 737 simulators.  The rectangular panels along the "skirt" are maintenance panels.
 

This is the crane that's used to move the simulators in and out of the bay.  It's on a track that runs the length of the entire room.
 

This is an older 757 simulator as can be noted by the "Rediffusion" logo on the back.  Rediffusion is a simulator manufacturer that primarily handles military systems along with Evans & Sutherland.
The vented panels long the rear wall of the simulator cab are used by maintenance crews to easily access the onboard electronics bays that contain most of the "black-boxes" that are used by the instructor station and avionics systems.
 

Now here is one to make you sit up and go "HUH?!".  It's a late 70s vintage ADM-3A serial terminal.
It sits right next to the fancy instructor station.  I have *no* idea what it's doing inside a 757 simulator, although it could be used by the techs to interrogate any onboard systems diagnostic software.
 

This is an interior shot of the 757 simulator.  As you can see, the avionics are active.  The white lines you'll notice outside the windows are the runway threshold lines as seen at Boeing Field.  The visual system used here is a Class D full daylight system.  This means that the light levels generated by the scenery computers is equivalent to an overcast day at noon.  Pretty impressive considering the lens system they use.
