Well, there are several 380's flying, and are route qualified on most routes early delivery customers will use.
If that's not working, I don't know what is.
As for composites, it wasn't long ago that the Airbus bashers were throwing a fit about it's use of composites, and praising Boeing for not.
They have completely reversed their positions now, convinced that composites are wonderfuuullll.
I thought it was only a couple, can you point me to information showing "several" A380's flying?
