OT - Being 787 issues, does this mean carbon composite has issues?

Hmm, which would be a little unsettling considering the magnitude of error
here. It begs the question, can we assume that there are errors somewhere
else yet to be discovered. Hope this do not end up being another DC 10
fiasco.

Welcome to the world of compromise!

Agree, A380 issues was somehow related to developing pieces of the plane
from both Germany and France. However, this would not have occurred were
both side using the same software vendor.  This begs the question, is it the
geography or the software politics that came in the way of A380? I tend to
think its the later.

Evan, the parts did fit in properly. Its just that, the complete system
started breaking up earlier. Why did you arrive with that conclusion?
