I believe that the reason for the re-dominance of Boeing, is partly having had their nose put out of joint by Airbus, which meant they went back and put a lot of money and effort into the 787, which has paid off well for them. Airbus, with all its good points was (and still is) riddled with the same political/bad management problems which affected the A380, which turned into a big white elephant. Not saying the A380 is a bad aircraft at all, just poor decisions with information between countries etc. They will sell lots of A380's once they start rolling out i would think though. Airbus having shelved the A380 Freighter really need that project to start up again, as there is no capacity left with the current pax wings, so to grow the aircraft it needs the freighter wings. And just to make you worry a bit about some of it, heres a couple of nuggets...
1) Forget the failing at less than 1.5 times limit, the local structure was already locally taken to ultimate previously.
2) Freighter wing carries only about 5% or so (i believe) extra weight, but there are bolts which have gone up 2 sizes
3) Some control surfaces were basically passed by test on the wing bend tests, which unfortunately do not have aerodynamic loads on it?!?!?!
As for the A350, well lets wait and see what happens, theres no money in the pot to pay for anything until they start selling aircraft again.
