Much more elegant, IMHO:

I'll be flying to Asia later in the year, for the TRANSPAC segments I'll be on the 777. Those are great planes, IMHO.

It’s certainly hard to accept that cracks in structural elements are not a safety issue. Maybe they mean it’s not an IMMEDIATE safety issue.

Ive flown on the top deck to Asia on Singapore Air (really cool) and on the bottom deck on Emirates (not so cool).

I still prefer the 747’s but its getting harder and harder to fly them

“Just an ugly beast.”

Not inside!

I flew on a Singapore Airlines A380 London Heathrow to Singapore.

GREAT accommodations, food & service, even in Economy!

...traced back to a manufacturing issue. Airbus has confirmed that it has no effect on flight safety.

I would love to believe this.

I'm not so sure, however. (Caution, I am NOT an engineer, so my opinion is merely intuitive reasoning.)

So, aero engineers, please help me out here.

Wing rib feet help translate the stresses from the skin (via the feet) through the ribs to the stringers and then concentrates on the spars and then the carry-through. Is this close?

If the feet are cracking, does this not mean that the stresses are exceeding the calculated loads (including safety margins); and that there might (might) be stresses that were not accounted for in design?

Again, I don't know, I'm just asking.

Dreamliner an albatross?

Lowest cost per seat mile double aisle aisle aircraft in the industry. More planes sold in the shortest time in history. Largest number of planes on back-order in history.

Yes, a real pig./sarc.

Ya don’t have to be an engineer to know that the plane wasn’t designed to crack - anywhere - at any time.
Forces are showing up of some magnitude and/or direction not anticipated. This would be understandable if the planes had undergone some unique maneuver or impacted some unusual object. But to crack under normal operations?...
Not cool.

Deja vu, all over again?

From a story published by Bloomberg News Feb. 2006:

Airbus said a wing of a 550-seat A380, the world's biggest commercial aircraft, snapped during factory stress tests at its headquarters. The company said the incident won't delay the first deliveries due by the end of the year.

Airbus had to make design changes to the wing after it failed just below the specified ultimate limit in a stress test.

While it was still on the drawing board, I projected the 380 would have the shortest lifespan of any craft in the history of the commercial jet fleet.

No worries, Boeing is producing the next version of the 747 (747-800).

I’m glad Fedex didn’t buy them. Wait until the ‘too short’ wiring problems arise.

I don't think they have many orders for the 747-800’s on the books but I'd defiantly fly with an airline that bought them..my hope is Cathay Pacific is going to buy them

I haven’t heard about the wiring. What is the problem?

Well, they started production in 2010 and there are, so far, over 110 orders. Most of those have been for the Cargo version. Lufthansa is one of the Pax customers.
