The Seattle Times: Boeing/aerospace: Airbus A380 wing ruptures in stress tests
Boeing simply needs to conduct a simulated wing stress test (instead of an actual test - just like Airbus did) and the problem will be solved!
…Dassault Systemes (NASDAQ: DASTY) a world leader in 3D and Product Lifecycle Management solutions, today announced that Airbus has adopted the Abaqus Finite Element Analysis (FEA) software from SIMULIA, the Dassault Systemes brand for realistic simulation, as its preferred solution for static nonlinear FEA.
This decision comes as a result of an extensive benchmark of several FEA codes. The Abaqus FEA software has already been successfully applied on the A380 aircraft program for structural virtual testing, and represents a first step in what is to develop into a longer term collaborative relationship…

Hardly... 
You're right though about the bailout but he'll require Boeing to turn the B787 into a Boeing Volt Hybrid with a veeery long power cord...

It was a little humbling to have Joe "Father of the 747" Sutter on my flight yesterday (although great to get the Boeing swag). In a brief chat with him I was reminded of the depth of design and testing that goes on in a new airframe launch.

I'm sure that was ethnocentric, racist, and homophobic of me but...Oh well.

I just thought it was funny how you managed to turn this thread about the B787 into a Boeing V Airbus thread.
Evidently you have Boeing as the clear winner while speculating that no Airbus will be in service as long.
I wonder what method you used to examine an entire Boeing aircraft including all non-Boeing systems against an entire Airbus aircraft including all non-Airbus systems. Do you have contingency tables and Venn diagrams with probability concepts available?
Or, are you just looking at this from a "pilot's" viewpoint and which ones you like to fly?
Since you've flown both, do you have the numbers on the economic life of each airfame? I wouldn't mind seeing the time on wing of each engine variant of both types too.
BTW, Boeing, Airbus, and all the associated US and Euro made turbofans are truly world class. That's a fact and I don't care what corner of the world they're made in.
I always find it funny when guys go to great lengths to proclaim who's the best, the greatest, the ultimate.

I remember while growing up in Russia a Tupolev that looked liked the Concorde ,I think it was the Tu 144. Nice looking plane .
As far as age is concerned I remember Fred telling me that he wondered if the dirt on the 747 he was flying was holding the plane together since the plane was over 16 years old .

This 787 wing thing reminds me of an old story I heard long ago.
During WWII there was a German engineer that was working on a new wing design. The only problem is the wings kept breaking in the same place no matter what he tried. He kept changing the wing design to resolve the issue but he just couldn't get it to not break. Finally, one night he was working late into the evening trying to figure out what to do, when he saw the janitor walk by. In desperation, the engineer asked the janitor if he had any ideas. The janitor, looking at the problem for a couple of minutes, suggested that they put some small wholes in the wings near the point that keeps breaking. This was obviously a strange idea, but the engineer figured, what the heck, nothing else has worked. Well, after more testing, the design held!!! Sure enough, the wholes fixed the problem. When the engineer went to the janitor and asked where the idea came from, the janitor said - Well, everybody knows that the toilet paper never tears at the perferations..........
