A very interesting bit by the BBC raises lots of questions and a glimpe of the saving to be made after just a 5-10yrs of investment.
"There are inefficiencies in the system," says Mr Ky, pointing out that in Europe there are 36 air traffic service providers and 58 en-route centres.
By comparison, in the US there is just one air traffic service provider and 21 en-route centres, even though it controls air space that is somewhat larger."
"Nevertheless, Mr Ky is eager to stress that sorting out the stuff that can be fixed could deliver savings and other economic benefits in excess of a whopping 400bn euros (£340bn; $545bn) - including the creation of 328,000 jobs - in return for a 30bn euros investment over a 15-20 year period."
It would seem to make sense but what chance of "Europe" working together on this one?
