Can the runways handle all the extra aircraft movements for DXB to be the busiest airport in the world? I'm not in the industry, but if I remember right the ORDs, ATLs, and JFKs all have something around five runways each.
Bit off topic, but what's the circular arrangement of buildings at the top right of the pic?
Also - any pictures of DWC?
Remember DXB is functional 24 hours a day, that's the big difference.
Sooner, or later two runways will become a problem with this kind of expansion
