Let's have more of the "can do" attitude upon which MAN built its early success. Now it seems to be a list of "well we can't do this because ..." Handling a cargo turnaround isn't rocket science.
But it's not as easy as that, if you're thinking about large freighters. Sure, it won't a problem unloading a "just in time" urgent shipment from a Cessna Caravan, it can be hand balled off. However you can't just put someone off passenger check-in onto a Hi-Lo and expect them to operate it, nor tow around pallet dollies, or drag pallets down the floor of a 747. if you haven't got the trained staff on hand in the first place just switching on a cargo handling service isn't going to be child's play.
