Boeing 747 Dreamlifter

[India Four Two]

A fascinating talk by Boeing test pilot Jerry Whites on the development and flight testing of the Dreamlifter. The video of the Vmcg tests (28:50 - 32:10) is particularly impressive.

The airplane starts to skate.

Fantastic! Well worth listening to and not just for the Dreamlifter details. The Q & A session that follows his talk is remarkable.

Good spot India Four Two, thank you for the heads-up.

[zetec2]

Agreed, a good hour or so's listening, amazing man.

Good spot India Four Two, thank you for the heads-upIt's because he reads other threads on Pprune.

[India Four Two]

megan, which thread did you have in mind? ;)

[treadigraph]

Enjoyed watching that with me cocoa last night!

So many good stories out there that need to be shared!

[megan]

megan, which thread did you have in mindI had in mind one of these, but the timing says you were well ahead, apologies.

I can highly recommend PeninsulaSrsVideos on Youtube, they have folks from all areas of aviation giving lectures, up to 1:20 in length.

megan,

Thanks. No problem.

I thoroughly agree with your recommendation about the Peninsula Seniors Videos. I just watched this one on the YF-23:

A few years ago, I visited the museum at Torrance and had a close-up look at their YF-23.

The interesting part, for me, was the open acknowledgement that the planning for bringing the components together was not thught of that early in the process. Unless he was adding to make his story more of a story - it showed up the problems that Boeing gave themselves in adopting the methods of Airbus at short notice.

Wheel falls from Dreamlifter on takeoff.

It made me think of Barnes Wallis. :)

[treadigraph]

Made me think of the dams raid too! Wonder how that came to happen...? Smoke or fluid visible as it departs? Edit: looking again, must be smoke.

Tyre blew and came spinning off its rim presumably. Probably when braking was applied at the start of retraction.

No, the entire wheel+tyre departed. Bearing failure, perhaps?

Not the first time a wheel has come off a 747.
Didn't BOAC lose one on TO in the early days and it landed in the staff car park damaging several cars including the captain's?

MJB's Twitter link not working for me now, but it's now on the toob...

I still don't see the video's in the posts. Is it possible to include the link itself, so that I can click it to see video's etc? Thanks.
(Anybody an idea, why I can't see the video's in the posts?)

Seems to be a fairly general problem on this forum Washoutt,there is a thread about it on the 'problems' page - it has been reported to the website owners !
It is (thus far LOL) the only forum that I have a problem seeing URL's - you can often see them if somebody 'quotes' the post or if you pretend to do do a post with a quote of the url.
Interestingly as I type this response - if I scroll down the page I can see the URL's :ugh:
But of course that only works until I save or post LOL

Try this link...

I vaguely remember this may have been a TWA B747. On another occasion at Heathrow, in late 80's I think, a Fedex DC10 on take-off lost a nosewheel , but fortunately the wheel remained within the airport with the only ground damage being a taxiway sign. Subsequent investigation discovered the wheel bearings on the nosewheel were from a B727 and not a DC10.

[tdracer]

The cloud of (smoke? dust? debris?) just before the wheel drops makes me think of a carbon brake disc coming apart...
Granted, if the wheel bearing was failing, if could easily damage the brakes.

In case it helps, for me the videos have disappeared while using Firefox browser but are visible when using Safari (both on a Mac).

You picked a fine time to leave me, loose wheel.
