Let's be practical guys, I've been around Boeing field a lot of times, I know that part of Seattle... there is no room left there and you have to go a way out of Seattle and away from the Sound to find enough land.
Don't get me wrong, I love Boeing and would love to save the plant. I live in Washington and I love the state and Boeing really did build this state. It's just that I would like to see Boeing keep plants in Washington instead of building them elsewhere. Our state government already ran their corporate HQ out of the state. I'm sad to see the old plant go but I'm willing to sacrifice it so Boeing stays centered around Boeing Field. That field contains a hangar/workshop that's constantly restoring aircraft for the fine aviation museum they have on hand. Boeing, ironically, is preserving the Concord for one. I'll take the trade off.
