Impressive machine no doubt, however one thing worries me about a composite passenger aircraft is the fact you can do serious internal damage to a composite structure without a lot of surface evidence to indicate whats happened in contrast to a conventional structure which hides nothing, problem i can foresee is it as happens all the time, catering /baggage/toilet truck smacks into the fuse, no sign of much external damage, culprit decides to say nothing which is not unheard of im afraid, couple of hours later crew/engineer does his walk round all looks well , but alls not well ,that structure has in fact suffered serious internal damage... , any composite experts care to comment.
I know there aremilitary composite aircraft out there but they tend to operate in a much more controlled aircraft friendly enviroment than you find at a lot of civil airports around the world
