Watch an Airbus A320 at any airport you care to with it's UK designed and built wings, engines, undercarriage, hydraulic system, fuel system, cockpit transparencies and seats.
CFM56 engines British designed and built are they? Not many people know that...The US Govt might be interested though.
Messier Bugatti Dowty (undercarriage) British, are they? OK, they're big in Gloucester but by no means all British or anywhere close to it.
UK has a larger aerospace industry than France/Germany Airbus? Does it?
