JF - possibly, that did cross my mind, but apparently not according to the person I was with at the time. Will dig around and see if I can find a link to a picture.
Its interesting to note above that flight sim pilots on their computer normally fly the sim seeing their aircraft from behind. Back in my youth I did that with MS flight sim, as I hated not being able to see sideways or have any peripheral vision.
In my experience there is a big difference between sitting in a fixed base sim and a full motion sim. Even if the motion is off in a full motion sim, ones brain is still fooled into thinking it is moving - in fact I was "flying" one with the motion off and the back door open. Looking behind me as the sim did some visual gyroscopics was quite disorientating. However most fixed based sims have poorer visuals, usually just a flat front screen. If this is the case it leads people to fly the screen, not the aeroplane, at least if they have no experience. This does not seem to happen in a full motion, or perhaps I should say full screen sim.
