Ok Imp, forget about the blackness of outer soace...

Think about how everything bends inwards when you look forward down a long desert road.

Now again I am making a guess but a guess based on angles and position of the mandible in the green on the left.

Ronster, although you amended your previous post to include your diagram with the coloured lines after I'd commented, it helps confirm for me the way I look at all these cockpit interior camera POV's - if you extend the middle *blue* line (showing the top edge of the 'mandible') towards the outer cockpit on your diagram (I just held a pen against it) you'll see that the top edge of the 'mandible' is actually a little *below* the side windows of the cockpit.

So that, taken in conjunction with your other helpful mock-up which I've shown above confirms for me that the 'mandible' would definitely be offscreen somewhere around where the 'tree' is seen on the far left-hand side...but still hidden by the lower section under the side window, if this was the view we were to see outside this particular camera POV.
