787: Unsafe Per Whistleblower In Interview

From an interview with Dan Rather to be broadcast tomorrow evening at 8:00 PM ET.

Quote:
Speaking only to DAN RATHER REPORTS, Weldon says that Boeing's
new 787 Dreamliner has major safety problems stemming from its
design and use of reinforced plastics -- called composites --
that will make the plane unfit to withstand survivable crash
landings.

Weldon describes how the composite fuselage will "shatter, not
crumple" in a crash landing.

I think he's whining about some core safety issues, which are the very ones Boeing would have addressed and tackled FIRST, and before any other engineering issues, when considering building a CFRP airplane.

I wonder what kind of ax he has to grind. Unfortunately (for Mr. Wedon), Dan Rather's credibility as a journalist is not much higher than a used-car salesman. I think he's just looking for some publicity.

Yeah and I wonder then how this aircraft could pass muster with 48 airlines and I also wonder how the A350 would fair as well? And what about all the military aircraft that have been built using composites. Sounds like he has an axe to grind and is trying to find a way to hurt Boeing.

What actually would happen to a 787 or A350 during a survivable crash landing'? Would the fuselage actually shatter thus sending alot of carbon shrapnel throughout the cabin? Or would the fuselage shatter sending debris away from the fuselage instead of in to the fuselage?

I wonder if this was the guy who was canned from Boeing a little while ago when he was found passing confidential info to the Seattle papers. I think Clickhappy posted the story.

If it is then the guy had a serious grudge against Boeing for outsourcing to southern states (Banjo playing yokels I think he called them) and to Japan.

Boeing have bet the farm on the 787, if it turns out to be another Comet 1 they're probably finished and they know it. Anyway we need Boeing to keep John Leahy honest (same as Boeing need Airbus to keep Randy honest)

Keep in mind when you read this that Rather has condoned if not been complicit in the journalistic equivalent of planting evidence. Maybe these purported safety issues are true, but I won't believe it until someone who doesn't have taint all over him reports it.

Boeing have completed three large-scale "crash tests" of the 787 and all three have been deemed "successes" by Boeing and the FAA and have been said to validate Boeing's computer models of how a 787 would likely deform in an accident.

While Boeing has not released the specifics, I would expect that it would be no more dangerous then an Al airliner.

No, Dan Rather was the guy who aired a story about President Bush going AWOL during the Vietnam War. Whether it was true or not (it doesn't matter), the documents used to back the story were in fact forged. When expert analysis proved this beyond a shadow of a doubt, Rather refused to back down. He didn't do the forging but he was guilty of not fact-checking and then (when shown up) not recanting. If he had at least backed down in the beginning, he wouldn't have been fired from CBS.

Regarding composites vs. aluminium, it is true that composites sometimes exhibit unwanted behaviour. At the recent crash-landing of a Danish Dash-8 Q400 the composite propeller shattered and sent shards into the passenger cabin. A metal prop would most probably just end up with the blades bending backwards.

I guess there must have been a lot of thought going into the construction of the B787, it seems highly unlikely that nobody would work on such an issue, so I'm certain that the composite has been enveloped one way or the other.

Whoa... whoa whoa... let's just slow down a second.

Does anyone here ever watch Formula 1? Great stuff, most advanced cars in the world with complete carbon-fiber chassis. Now has anyone ever watched one crash? They do send carbon fiber splinters everywhere and they do shatter.

The last time I watched a crash (Kubica in Montreal, fantastic crash) I wondered about the same thing regarding the 787/A350. I don't think it's something that isn't worth discussing.

Granted, the F1 cars are still very safe with their carbon fiber chassis, and granted an airplane with a company as huge as Boeing behind it is going to go to great lengths to ensure its safety, but I think there can be no doubt that the nature of a 787/A350 crash would be a lot different than a crash of a metal plane.

Yes, I would hope that they would have run numerous tests on the frame (however the recent fuselage test that passed doesn't address what this guy is talking about), but I still think it's worth discussing instead of just saying 'bah!'.

Carbon fiber is stronger than Aluminum and Boeing usually overbuilds things at first anyway.

There there have only been 6 or 7 hull loss accidents of a similar sized plane (767) as of 2005 with 568 fatalities. In most of those, the splintering / cracking of the fuselage wouldnt have made a difference. Is this really that big of an issue? When planes hit the ground they pretty much break up quickly, a la the Phuket crash, where the plane "crumpled" and still broke up.

The 787 will have the most advanced avionics ever in a commercial plane, so hopefully fewer crashes will happen anyway.

Is "shattering" CFRP less efficient at dissipating energy than "crumpling" aluminum? I don't think we can make a blanket assumption about that. The premise of the accusation is doubtful right at the outset.

Airliners could be safer if the fuselage was armored, exit doors provided for each row, airbags in each seat back...you name it! The resulting Volvo of the sky would be too heavy to carry a useful payload, at least at what we consider reasonable ticket prices.

We knowingly exchange some degree of safety for efficiency...true of cars, buses, trains and planes. yes

Of course it's worth discussing. The issue is, why is this guy the only one that is raising flags about it. Also, it appears at first glance to implicate Boeing in some major cover-up. Is he the only one that is aware of the properties of CFRP when destructive forces are applied to it? Does anyone think Boeing conveniently chose to ignore it? What about the FAA?

I wonder if his "ax to grind" isn't that several of those guys who used to spend so much time riveting aluminum panels to the aluminum frame in Washington are now out of a job because it won't take as many to bolt the few plastic sections together. If you Build your whole career around aluminum then it'd be hard to love CFRP when it doesn't pay the bills.

Also, Dan Rather's only problem is that he really made Republicans angry. It's not getting the story wrong, but telling the story with forged letters--for which he did apologize. If false reporting was a crime, then every anchor on Fox News would've been jailed long ago.

Not saying that other media outlets are necessarily better, just saying this one is crap. If this story shows up in the WSJ or FlightInternational or AvWeek, fine, I'll believe it. Dan Rather is not in the aviation reporting business, not in the financial reporting industry, and has a stink about him.

By the way, you are wrong about one thing. Rather stands by the documents
