They have taxied down 16R twice now, looks like they are getting ready to do a high speed. I alerted the local news so there should be a lot of pictures very soon
The grounds will be interesting to watch - especially if there is continual increase in speed. As I recall, the 777 lifted off a bit during testing on the day before FF. I'd bet my left one that some test pilot will be tempted . . .

As underwhelmed as I've been in the overall appearance of the 787 (I like it, but haven't really been overly inspired), and as disgusted as I am with the debacle of a program it has turned out to be, I must say that I found the overhead video absolutely stunning! What a great looking aircraft when it is actually in motion.

I agree. In Auburn at the Supermall cinemas there is an airplane/airport theme. On the wall is a likeness of a 777, but it always looked a little off. Oddly enough, I think it is proportioned almost identically to the 787.

"Test pilots were taking the 787 for a low-speed taxi test around Paine Field's runway and taxi lanes. They were checking the steering and braking system, a Boeing spokesman told KOMO News. It's the first time the 787 has moved on a runway under its own power."

I tend to think it wasn't a full RTO, but more of a braking test.
When I used to work around PAE, I'd occasionally see a 777 really rev up the engines with her spoliers deployed and motor about a third of the way down the runway then hit the brakes and idle-back the engines. She'd then taxi off over to the flight line where I expect engineers would take a look at the results.

Indeed and RTO test is usually done with fire crews standing by on taxiways.
Also no way that it could achieve V1 seconds at less than 10 seconds from spool-up, even on an empty plane.
Congratulations to Boeing and all the people who work(ed) on the 787 program for this milestone, the first true milestone.
It is not flying yet, but the skies are getting closer and the 787 truly is a gorgeous aircraft.
We all hope to see this airplane flying very very soon!
And indeed, we all deserved that bit of tire smoke, proof that the 787 is starting to live.

Given that the Wright brothers first flight was probably not even one 787 long, if it takes off at a few feet altitude for maybe 3 seconds and then touches down again... would that not count as a first flight?
Great to see it moving... very much enjoyed seeing the 787 on the production line when I was at Boeing in January.

My first thought was more they puffed smoke as it was the first time they were really being used, maybe it sitting idle for some time let to some dust build up etc they got burnt off. Or they were going faster than reported (slow?) or were having so much fun they had their first oh &(*@&$ moment and saw the end of the runway approaching quicker than they thought?

Don't believe anything you read on the net. Except this. Well, including this, I suppose.
Air Force One Ship 2900 was also there. So this morning, minutes before we had the Boeing Factory tour, Air Force One took off. Great!
Minutes after the tour, 787 #1 did some taxiing test, nothing spectacular there but still nice to see. Minutes after, the beast had several brakes test at medium speed, around 60 knots. It was a somewhat smoky test.
Minutes after one of the two Dreamlifter took off in front of us. Great.
787 was resting in a taxiway for brakes cooling. Another set of brakes tests were done. It was supposed to occur at a higher speed, around 90 knots. For some reasons, it was done at the same speed. Quite a show!
I also had a very interesting discussion with guys involved on the project. I'm definitively lucky
In the meantime, some nice activities in PAE, with 737 touch and go, go-around and various GA planes on the touch and go loop.
I'm currently off-loading the camera and will keep you guys informed.

I think that ad should change to "Time to Make Some Howling Friggin Jet Engine Noise".

Nice clarification, appreciate it. Could you confirm that SAM 29000 is configured just like AFO? I ask that because I noticed some missing components (with my limited knowledge of that matter) like antennas and others "bumps" on the top of the hump?

It is Air Force One when the President is on board. "Air Force One" is a callsign, not an aircraft. The 747's that are commonly called Air Force One (there's two of them) are VC-25A's, as Glbltrvlr noted.

With credible reports emerging that there could be another massive delay looming for the 787 (up to 18 months) and with a significant structural redesign currently underway, I get the feeling Boeing is still listening too much to their spindoctors who might have had a worrying look at the calendar at the wall and have seen that today is exactly 2 years after the notorious potemkin roll out event of 7/8/7....
What better way to try to get at least some positive reports out in the media on a day like this than by being able to present at least some visual progress in the form of these taxy trials on the day before?
Let's face it, there's just too much coincidence in them timed the way they were, especially as they're not in a hurry: there won't be a 787 in the air before this autumn at best; the fact it is done really gives away the fact Boeing still hasn't turned the page, hasn't changed mentality and is still trying to cook the reports.
Very worrying things indeed from a company that rolled out a new plane and then had to announce it was nothing but a sort of mock up a few weeks later, or said the 787 would fly in the next few days at this year's Paris Airshow only to admit it wasn't remotely airworthy a few days later... Yep, first taxy trials yesterday: seems like Boeing is right on schedule to announce another massive delay on the 22nd of July!

@Slz396
Even if the problems are as big as reports indicate some experts to fear, there is no reason not to test all those components that can be tested, and to test how they work together under real conditions. So make many brake tests as example to verify the brake system or to learn more about it so that time that may be available can be used as efficient as possible to improve the aircraft. I don't think that the wing to body problem is so massive that there is the danger the body slips of the wings as soon as the aircraft brakes.
If the tests now would not make at least some technical sense, Boeing would either have skipped them or annouced with a lot of marketing noise.
IMO Boeing needs to test, analyse, verify and re test as much as possible as soon as possible. Regardsless of the wing issue. You can''t find a snag too early..

Somewhat disappointing that you couldn't resist raining on the parade, but I guess it's to be expected.
In my opinion, if you can do the tests, you do them. The plane is going to have to go back in for modifications at some point - you do what you can do now so as not to waste any time.
One thing I'll say is that, if I were Boeing, I wouldn't be trying to draw attention to a date that screams "We're two years late today. Happy Birthday." I would be going about the business at hand, and it appears that that is what they did.

I do agree that Boeing has, in the past two years, put too much emphasis on PR and too little on engineering. But I don't agree with you concerning the taxi tests. The positive PR that will come from this is negligible. The flight test department was supposed to have the plane in the air by now. What are the pilots and the flight test engineers supposed to do?

Not too sure about "locking" the brakes. I dare say the 787 is fitted with an ABS system like most contemporary types. IIRC, when they do the formal maximum energy RTO test, they will need to use brake units that have been worn down to the replacement limit.

The ABS systems don't completely eliminate fraction of a second lockups. You still get some smoke at 100% braking.
They might be running them to the limit to verify the fix on the monitor that they had to change to keep it from overheating or just to measure temps with max braking. Smoke might also be normal the first time you get everything red hot with new brakes. Just like all the oil burning off the engines the first time they're lit.
There's no secret memo going around the test team with the new flight date. They still need to proceed like it will be ready to take off any time.
In the years I've been monitoring this site I've heard some pretty baseless claims, but the insistence of some that this will require a ground up redesign of the wing has to top everything. Is there some sort of secret CaptainX fan club or something?

I agree... it just wouldn't make sense to do it at this time for publicity purposes. Doing what they said they would do (continuing with the tests while they design/implement the fix) is what makes sense. If the gauntlets and the taxi tests were not done, people would be all over the thread speculating on what else is wrong (as if there wasn't enough already).

I dunno, common sense would suggest that if they are going ahead with taxi testing, first flight could be closer than we think. Why continue testing an airplane that is going to be delayed another 18 months? The tests would have to be done again in 18 months time. There is probably a better chance we will see if fly SOONER than later.
However, on the other hand, we have seen Boeing pull some real stunts over the past two years, so anything could happen.
Again, what happened to these 18X2 patches that were going to be placed around the stress areas on the wings? I thought they were going to solve the problem. Have we heard anything more on this quick fix?

I assume that both A&B wear the brake units down in testing before the max RTO test. That would seem logical, making the first trip to the runway a basic test.
Quoting Nomadd22 (Reply 87): the insistence of some that this will require a ground up redesign of the wing has to top everything.
Well, the 380 didn't need a full redesign of their wing. They calculated the fix and installed it. At some point (18 months later?) new production planes had an "improved" -v- "fixed" wing. Is there any real difference with the 787? A fix for existing planes and an improvement for anything new starting production?
I'm not an engineer, but I believe we'll see several things:
1. Continual non-flight testing as if things were going normally.
2. A fix for existing planes, with the fix installed as soon as practical.
3. Several 787s ready to fly as soon as first flight is completed - all with fixes.
4. An improvement engineered for all new planes, with the first "improved" planes exiting the factory in about 18 months.
5. One (minimum) of the two initial birds "lifting" off a bit in high speed tests - but not "flying".
6. Boeing's stock improving a bit after first flight. Seeing the first 787 in the air will make Wall Street very happy.

Quoting Slz396 (Reply 83): Excuse me for pointing out the coincidence of this first taxy trial happening on the evening of the second "Potemkin roll-out" aniversary...
Sorry, Slz, but we're past the "I'm just an innocent a.net member" period. Frankly, your entire post had nothing to do with a taxi test and everything to do with the opportunity to bash the company again. Do you have nothing else to do with your time???
Quoting Stitch (Reply 90): I don't see why Boeing should just close-up shop and send everyone home until ZA001 is ready to fly.
Other than making a few a.net members gleeful, I can't either. I wish it were a clear indication of a first flight coming sooner than later, but I doubt it's anything more than what it is - making every minute count. I still enjoy watching the first A380 flight on Youtube, and hope that the 787 is every bit as enjoyable.

Quoting Stitch (Reply 11): I think the 787-9 will be better-proportioned. She looks a little stubby forward of the wing.
I agree with you Stitch. I think the same thing with the 767-200 versus the 767-300 versions. I think as well the size of the cockpit windows, the larger side windows and size of the engines, the 787 looks smaller than it really is, and gets the chunky look you mention.

Quoting Keesje (Reply 79): What everybody wants to know but doesn't ask to not spoil the party I guess. There were some issues with the braking system. Software last yr, further changes were announced earlier this year.
But you want to try to connect the two, without knowing ANY information on the nature of the test, including whether it was something like an "ABS Fail" test, one that would lock the wheels and create tire smoke. Or they could have purposely recreated a fail condition that the software had trouble with last year simply to confirm the change is correct. Who knows?
I've also never seen the initial braking tests for any new aircraft type on video to have any comparison to. Have you?
The point is, we don't know and you don't know.
Of all the things to worry about... the Wookie has no pants.

One big difference is that Boeing didn't destroy the test frame in discovering the problem, so they can do a real world test to verify the fix. Airbus had to convince regulators that their model was sound and the fix would take care of the small amount they missed by.

Quoting Ikramerica (Reply 12):
I also think the paint scheme helps make it look short. the plane looks a little better in the NH livery.
Definitely! Saw the scale model last week in the ANA lounge at Narita. A real beauty. I felt a bit sorry for NH though. Suffering the delays as the launch customer and at the same time seeing SQ steeling the show at NRT with the A380. I know the two don't compare and it is all about profit but still..........
Would be great to see the 787 at airports around the world.
There's still a long way to go before all the alliances deserve a star...
Very, very nice. Thanks for posting this link of the beautiful B787 in taxiing action. Your next video link should of course show us the B787 in the air.

Wasn't that Ken777's point, in support of yours?
Airbus failed a complete wing (destroy a test frame is a bit OTT IMO), but still didn't need to re-design the wing.
Hence Boeing shouldn't need to re-design the wing when having a substantially smaller failure (would you call it "nearly destroying a test frame?" )

4. An improvement engineered for all new planes, with the first "improved" planes exiting the factory in about 18 months.
Scott Hamilton quoted Carson saying that only 40 aircraft would be affected by the temp fix, which would then mean that the average production rate over the next 18 months would be 2 aircraft per month?
If we assume that...
- LN1 to LN6 have a center wing box with a temporary fix due to the previous issue
- LN7-LN19 have a redesigned center wing box addressing the previous issue
- from LN20 onwards the 787-8 will have an increased MTOW of 227,9t, which amongst others requires a strengthened wing and center box...
would that mean that we see a one-size-fits-all temporary fix for the wing-body-join issue that is applicable across the first 40 aircraft?

Quoting Nomadd22 (Reply 87): The ABS systems don't completely eliminate fraction of a second lockups.
Fair enough. I thought you meant sustained lock.
Quoting Nomadd22 (Reply 87): You still get some smoke at 100% braking.
Sure, and you can smell hot brakes from a distance as well.
Quoting Ken777 (Reply 96): I assume that both A&B wear the brake units down in testing before the max RTO test.
I think it is a regulatory requirement, thus A and B would have no say in the matter.
Quoting Dragon6172 (Reply 100): Any possibility they would disable the anti-skid/ABS for initial taxi testing to make sure the crew had full use of the brakes?
Possibly. In normal operations, however, ABS will give the maximum braking performance for the prevailing conditions if required.

(its too early to pop this but a good time to buy so that it will have to be popped eventually 
I agree... it just wouldn't make sense to do it at this time for publicity purposes. Doing what they said they would do (continuing with the tests while they design/implement the fix) is what makes sense. If the gauntlets and the taxi tests were not done, people would be all over the thread speculating on what else is wrong (as if there wasn't enough already).
