I recall chatting with a C-130 maintainer long ago, and the discussion turned to C-130 center wing boxes. He pointed out that the C-130, C-141, and C-5 all had to have some form of wing box redesigns or replacements over their lives.
What is it about Lockheed that they can't design a proper wingbox?
