PriceWaterhouseCoopers has released its latest analysis of attractiveness for aerospace manufacturing, ranking both US states as well as countries. The United States remains #1 in the world, due in large part to the concentration of the global industry here. North Carolina ranks 7th overall, while Washington State, Georgia and California hold the top three spots. Interestingly, South Carolina, home to Boeing's east coast manufacturing facilities, ranks in the 20's.
