While I agree with most of what you have written, I must take exception
to your comment that we didn't have to design and build new fuselage
tooling.  That is just wrong.  Here in Wichita, we are using completely
new concepts (WRT the classic line) in tooling and assembly for the Next
Generation 737.  All of the 737 NG aircraft are being built on
completely new tooling in a different area of the plant than the Classic
line.  I should know since I was involved in the groups which designed
the Sections 41 and 47 (cab and aft entrance/galley area), floors, and
struts for the new aircraft.
