SamYeager -
Good question. I haven't read anything that excludes 787s assembled not in S.C. from the pertinent manufacturing defects. The timing of the more intensive scrutiny does suggest the possibility that the other manufacturing site hasn't been accounted for sufficiently, with regard to these defects. (Several posts early in this thread suggested that the defects identified were in sections in S.C. - nos. 7 & 13 for example, but obviously that doesn't exclude the other site from problems.)
As for relocating back, okay that won't happen. Maybe posters who have advocated tearing the company down and selling off assets, letting someone else start from scratch, will prove prophetic.
