Hi Tim
I will use the following image's to explain apparent
first image is of what LOOKS like shell of cockpit viewed from left side the right side as you can see has a big rock bashed on top
A, edge of roof hatch
B, right hand side of cockpit window
C, big rock on top of left side of cockpit window
Now second picture from about same distance, showing little tree's in odd straight lines, So now if you use the small tree's for scale, unless they are palm tree's, Your wheel is no bigger than a steering wheel
Thanks Richie
