What about NG birdstrike protection? What about a fatigue tested wing? What about sudden decompression protection? What about cabin direct view rules? All, of course, to the mid-90s standards, and not those of the mid-60s.
Should I go on? These are all questions that I'd love to have an answer to.... and answers are not forthcoming from Seattle.
Now, let's talk again about the A380. It will HAVE to pass an evac test if it is to ever be sold to a U.S. airline. As there's really only 1 making use of 747s today in any decent numbers an who doesn't have most of it's fleet parked in the desert, maybe that's no big thing. However, I'm sure the EASA will insist as well, won't they? As BahrainLad sasy, the forerunner of the EASA demanded that the 346 be reworked, so they are tight about that sort of thing. If it has to be done, I'm sure it will be done.
I note with interest that the stones from the glasshouse have stopped (temporarily).
