RobRoy,
That huge facility was also 15% of what the Everett facility is. Majority of it was engineers. Who BTW I know of quite a few who are now $20k higher a year in pay and working at Everett for $80k a year. Not bad apples.
Renton facility was always a drag on Boeing as the Eastside values as well as constant issues with DOT, and a myriad of other issues made it more effective to move a lot of the administrative to Chicago. The actual industrial work went to subs or got moved to Everett.
If you have anything to back up moving Everett facility which is once again the largest industrial complex in the United States please state some of the facts, oh BTW and there is an airport attached to this one the size of SeaTac.
