Sorry Bagso, this is getting a little tiresome.
Only a fool would say that the problems of runway capacity in the London Area can be solved by more flights at Manchester or anywhere else for that matter.
Also you're wrong in your assertion that EMA is the 'most significant for cargo in the entire country'. LHR is. Why? It's because most cargo is flown below deck on scheduled pax flights. You're getting confused with freight only flights.
