If I were you - I would not get so excited. Sure it "may" happen in December, but how many times have they changed their minds? Lets just wait till she supports her own wait to get excited.


Keep the shinny side up!

Early Christmas present? We can only hope! Hopefully this is the beginning of the end for problems on the 787 project for Boeing. They have gone where no one else has gone before; it took a bit longer but I think we will see this girl up in the air before the end of the year  Smile

Unfortunately we've been here before many times -

"Boeing declined to confirm the completion of the installation..."

So, Boeing is NOT confirming the work is complete.

"Sources also indicate that the wing fix is slated to undergo full-scale testing on the static airframe..."

The fix has NOT been tested yet - they are hoping, as they were the last time, that this fix will be THE fix.

Keeping fingers crossed but breathing normally.

Well, let's just hope they got the predicted date right this time. But Boeing still not confirming anything makes me a bit skeptic. But I hope she will fly even before Christmas.  Smile I will believe it when I see pictures or a video feed of the B787 taking off or being airborne.

Given the whole saga of this plane, I'm not going to hold my breath!

Shes is a good looking bird and I'll be happy when she finally fly's but I'm not going to die for her!

When the results of the static test airframe tests are in, then and only then make an announcement regarding when the first flight will be. Boeing is setting themselves up for more embarrassment if the static tests don't produce the right results. Someone please tell me where common sense has gone.

Boeing hasn't made an announcement and that was clearly stated in the post. 'Program Sources' are not official announcements. I suspect that Boeing is using common sense as they have not issued an official statement yet.

The fix has not been *full-scale tested on the static airframe.* That's quite a bit different than "not tested." Why in the world would you go to the trouble of installing a fix you hadn't tested?

Not to mention if they hadn't done any (smaller-scale) tests, how would they have known that Stringers #2-5 needed redesign and additional reinforcement?

I disagree. As we all know, and as Boeing discovered so rudely, anything less than a "full-scale" test might as well be untested. All the "testing" Boeing did on the fix beforehand turned out to be woefully insufficient and simply failed to deliver the flyable bird they had expected.

Once again, Boeing is hoping they have solved the problem, but there is only one way to find out: test it.  Wink

True enough, but then many people will take the words of "program sources" and construe them to be official words from the company itself. That does happen, unfortunate as it might be.

Of course, that is to be expected when embarking on such a task. I wish them well and hope they can make it prior to years end.

OK, I'll bite...

My question is... What year?

Further thought brings up the question of... and by which calander?

Or to more clearly state my belief.... "I'll believe it when I see it... " Then I'll find some calander that that date falls into the end of the year...

It is not that I don't think the 787 will fly. I think it will. I also think that overall it will be a success and allow Boeing to leapfrog Airbus on carbon fiber technology for other planes (but that may take a decade).

It is just that.... hmmmm.... there seems to be, in my mind, a credibiltiy issue here (and just to be fair - I also believe that Airbus has a similar one on the A380. Note I don't wish to get into an A380 discussion here).


You all have a great day...

Looking at the picture in the flightblogger post, it looks more like a "garage size" project than the A380. It feels like you can just bring your stool and start working on the thing!

Anyway. Let's hope it eventually flies.

Both programs desperately need to make first flight, if only to reassure their customers and send a positive message for a change. Let's see who surprises us first - because unfortunately a first flight of any of those aircraft would be a very big surprise indeed.

I myself think that at this stage it would not matter much if the deadline was just missed *by a few days* into 2010.

A different matter would be if a fresh delay was announced of course- but if it is just the final preparations running a bit longer than anticipated but not due to a new problem, then it will be of little significance.

Fingers crossed that once she's finally in the air the certification programme runs smoothly and no significant new problems arise.
