Boeing is surely taking a big step with the 787. If it works as expected, they'll sure get more than 50% market share in each segment they compete in.
But if something gets wrong? For example the fire resistance of CFRP appears to be quite low (imagine AF A340 crash last year with fire spreading fast, and lost of smoke: how many people would have remained in the plane?). And there is the delamination problem, and probably many more not even yet known. If problems appear before certification, it certainly means delays. If problems are discovered, say, 5 years after EIS and 500 planes are grounded, this will be a serious situation for Boeing.
Isn't it safer to go step by step: first wings with AlLi fuselage (and may be a smaller market share), then complete composite? I am not saying Airbus in right if they go this way, I am just asking.
