OzzyOzBorn,
It seems to me, as a mere mortal with some business experience, that businesses play to their strengths and MAG management appears to believe that MAN strength lies in passenger operations, while EMA's strength is cargo. If you ever visit EMA you would probably be amazed by how comparatively poor the passenger/terminal facility is, but thats because the investment has gone into cargo.
I would agree it does appear odd that an airport at important as MAN apparently doesn't have a main deck wide body cargo loader, but that investment would surely have to come from a handling agent. BHX has the equipment since it has a small but thriving specialist cargo handling agent that invested in it (Blue City Aviation). Perhaps the way ahead for MAN is to find an entrepreneur willing to do likewise there?
