They've been planning on gettting mostly out of WA because the BS for years, I think this will be there ticket out.. Boeing was a great place to work at, at one point and time, now its just a high paying job after you've been there 6 years, IF you can make the 6 year mark. Im a 3rd generation Boeing employee and remember when it was family oriented and cared, now you're just a small cog in a large mechanism it seems.
