Boeing 787 Passes Incredible Wing Flex Test
"During the test, the wings on the 787 were flexed upward “approximately 25 feet” which equates to 150 percent of the most extreme forces the airplane is ever expected to encounter during normal operation. The test is used to demonstrate a safety margin for the design and is part of the certification process to show the airplane can withstand extreme forces."

glad to see they succeeded in correcting the previous wingbox/wing join problem that led to buckling and <150% failure.

Did you know the A380 wing test failed just short of the 150% load factor? Airbus engineers had to go back to the drawing board and came with mods to beefen up the wing in certain spots. They decided not to test the wing again and presented a computer model or data showing it meets the 150% load. The FAA and JAA recluntly accepted the computer model data, in which they wanted a new test on another wing with mods installed to prove in the real world it passes.-Chris

Fair enough
So just to level the playing field and the original topic was about the 787 Dreamliner, but you guys always have to bring in some derrogative remarks about Airbus....let's look at the 787:

"2009 saw more A380s deferred in a single year than had been ordered in the last five years as premium traffic collapsed and excessive capacity started to be chopped from the system. Already sat in the biggest forward-loss position in the history of commercial aviation, Airbus stands to lose out further due to the impending WTO case lodged by the USA and many even have to pay back the subsidies that have propped up this unwanted airplane.

The premium market is dead, not a single A380 customer is making any money with it, despite the PR spin from Airbus (as is expected) and one of the biggest customers, Qantas, is cutting First Class seats for economy traffic as it foolishly trades yield for low end volume and zero profitability.

No one is talking about early A380 deliveries and Airbus' production system remains a shambles."

The article you quoted has this little seemingly overlooked part:
Analyses are solely the work of the authors and have not been edited or endorsed by GLG.
Just to point out some facts:
The CEO of Quantas himself was on the News just recently and stated:
"Due to the economics, 1st class and business seats demand have declined sharply, which has a large impact on the profit margin of the company as these are the most lucrative parts in the business."

There was no mentioning of the A380 specific, but simply a statement in general including "all" aircraft models used.

It seems your author just "tailored" it to suit his agenda.
No one is talking about early A380 deliveries and Airbus' production system remains a shambles.
So does the Dreamliner, it's already way behind schedule. It seems to be a common occurrence in the aircraft industry.

Why not just stick with the topic, which is the 787 Dreamliner?
I am looking forward to see the 1st one arrive for real here in Australia.

Glad someone is happy, cause there is about 60k workers here in WA state that are extremely pissed off! On the flip side the workers and their unions brought this action upon themselves...
