Is there any synergy between Broughton and Belfast in wing design and manufacture ? Ironically, 60 years ago, the Belfast plant (then Shorts) was a subcontractor to the Broughton plant (then De Havilland) for the production of Comet fuselages.
I remember reading a while back that that the ex-Shorts plants building the C Series wing was one of the most efficient plants in Europe and the prospect of a Broughton-Belfast centre of wing excellence is intriguing.
However, I guess we should remember that, insofar as I understand it, Airbus aren't buying the factories - just a majority share in one of the products made in them. The Canadian and Belfast plants will still be building other Bombardier aircraft parts too. Still, they should benefit from Airbus's expertise.
