After working many years on passenger aircraft, I would feel very uncomfortable flying on anything with a complete carbon firbre skin.
Especially considering the amount of hit-and-run incidents that occur to airframes by people maneuvering ground equipment. Human nature, IE; people too scared to report a mistake.
All it takes is a good bump to seriously weaken a carbon fibre material, damage that may or may-not be detected by the human eye, and then you have an accident waiting to happen.
I know more and more aircraft outer structures are being made by this material, but an entire fuselage? Come on.....
