Your opinion on this landing

They pull those wings up at the tips, no?

I've seen a few videos of airliner wings stressed to failure and when they
fail it looks like a small explosion with debris flying everywhere, but
much of that is the test apparatus flying around. The failure occurred at
a point. It simply isn't possible to design a wing perfectly enough or,
harder yet, assemble it uniformly enough to get a distributed failure.

No. Not in the test I saw. They pull up at various points along the
wing, simulating normal wing loading.

This might be the test you recall Jose. I would have to agree it was hardly
a pin-point failure, and certainly not at the root. Seems to be a pretty
good example of a well designed wing.

God doesn't play with dice, his dice just have a lot more sides than
Einstein understood.

No, this wasn't it. What I recall (IIRC) was in German - maybe it was
an Airbus wing. There were three views, I thought I had them on my hard
drive but alas, I don't.

Nonetheless, this one is similar in that the failure happened all at
once, all over.

Well, yes, but at the time of failure, the rest of the wing (in the test
I saw) was stresesed very close to =its= breaking point, so once it let
go wherever it did, the other points also let go.

Not likely with an aluminum structure. The failure will quickly lessen
the stress on the remaining structure and it will not self-destruct.
I'm still waiting to see the video of this self-destructing wing. I'm
betting it is urban legend, but if there's proof I'd love to see it.

You need glasses and a hearing aid. At about the 3:27 point the wing is
clearly shown with a kink at one point and the narrator says that the
other wing failed at the same LOCATION (not locations) but wasn't
visible. Sure, some of the skin flew off above the failure point, but
the entire wing didn't even come close to a uniform failure.

I remember seeing a show on the making of the 777, and it was in a giant
wing testing rig, and it failed as was predicted at some certain spar
number, but a bunch of the rest blew apart too, since when the one place
failed. all of the stress was transferred to many other locations.

That type of failure is the only way I can see it all failing at the same
time, too.

The odds of the whole wing failing at once is......Astronomical!

It clearly didn't fail at a single location, and certainly not the root like
you predicted, your trollyness.

Go away, you are starting to sound like MX in drag.

IT is not an urban legend. I have seen it.

Well, it's not an urban legend unless I'm also an urban legend.
