Thanks, Boradan. I added the none and that's stopped it displaying on mobile (seems droid Chrome suffers the same issue as Desktop Chrome - cache just won't let go - still showing it on my phone). Changed to fixed.
The vertical menu is the one from Offlajn.com
offlajn.com/vertical-menu.html
and it was them who said to add that code to make the left bar/menu reach to the bottom.
A good landing is one you can walk away from.
A great landing is one where you can reuse the aircraft!
======================================
Cropping the picture JUST above the tallest guy's head would remove the necessity for that as its currently a bit too far.
I noticed that on the picture in mobiles, there is a black gradient bottom to it.
Maybe do that to the larger picture currently used in desktop mode (along with the top cropping).
Then in the Parameters > page set the following:
background: fixed
x:0
y:0
adjust: full width
That will allow the same image to scale for all viewports, and blend into the background color for mobiles/tablets
