"It's entirely possible that the airframe as tested will be sound, but the production process may well cut the odd corner as cost and time savings are chased resulting in some undesirable results.
I, for one, will not be going near any Dreamliners until they've either been in service a few years in quantity without mishap or they've had their high profile disintegration and the realisation that this is one production process that cannot be sweated for cost/time has been beaten into Boeing's corporate mindset with the cluestick by the NTSB."
While I take your point (which is entirely valid) I would be far more concerned about airline maintenance departments taking short cuts and/or rushing repairs to the airframe after various incidents (such as vehicles hitting it while at the gate). Clearly composite repairs are not as simple as repairs applied to traditional airliners. I did read that Boeing had, or were, developing a quick type fix 'patch' (similar to speed tape I guess) for such incidents but a proper repair would of course be required.
Boeing are in a way quite literally betting the house on this airliner, if they start dropping out of the skies Boeing will be in big trouble. I am sure they are all looking at the bigger picture here and realises this is what production shortcuts could realise.
I sincerely hope this airliner follows in the 777's footsteps with production and safety qualities - if it does indeed manage too it will be a fantastic achievement.
Let's also not lose sight of one thing, many components on 'traditional' airliners are made from composites, including key wing parts, parts of the tail etc.
