So was the BAC Comet:rolleyes:

Let's take out all the fluff and reread this...my comments in blue

Quote:

...fire aboard a 787 Dreamliner (on) Monday...

...firefighters ripped out and tossed a burning high-energy, lithium-ion battery onto the tarmac...

The incident caused "severe fire damage"...., the NTSB said.

Chief (Boeing) Project Engineer Mike Sinnett...gave details about...four previous incidents...on 787 passenger flights...were more than the false warnings previous reports had suggested.

....the first of the problems occurred last summer. The incident wasn't made public...

...the issue occurred again in December on a United flight that had to be diverted to New Orleans; a few days later on a Qatar delivery flight from Everett to Doha; and then again on a second United jet.

...all four incidents were traced to faulty circuit boards...

...the flawed circuit boards are manufactured in Mexico...(well now THERE'S a shocker!)

Boeing is still working to fix that problem. (<----Still, eh? They've known about it since last summer.)

The Logan fire incident is much more serious. (Fires always are. Are they gonna wait to ground this plane until this happens in-flight?!? Oh wait, it already has! Derp derp derrrrpty derp!)

(When) United inspected its Dreamliner batteries after the Logan fire, it found faulty wiring installed...

The NTSB now has three safety investigators examining the cause of the Logan fire

Let's see...(from back to front)...

"discovered faulty wiring installed"

"traced to 'flawed' circuit boards" (hecho en Mexico)

"(earlier) incidents were more (serious) that the false warnings previous reports had suggested"

"first incident occurred last summer"

"incident wasn't made public at the time"

"issued occurred again in Dec....then again a few days later....then (yet) again..."

If it looks like thermal run-away, and smells like thermal run-away.........

The good news is that the containment box appears to work.

So....can someone tell me what part of lithium-ion batteries and plastic doesn't mix that Boeing doesn't understand?:rolleyes:

Btw, cardiomd, you my kind sir may have missed your calling. I'd go to the IMPROV to see you any day. I'm still ROTFLMAO!:D

You don't want grampa catching on fire after being hit by a baseball thrown by junior.

Thanks. I thought nobody was paying attention. :)

Of course, any scenario like that would doubtlessly happen in the absolutely funniest way possible, with gramps screaming "C'mon kiddo, put some heat on it! Put some heat on it!" before getting struck by the wild pitch and igniting. In the ER, Dad comes over and says, "well, he always wanted to be cremated, maybe now we can get a discount." Junior spends many, many years in therapy and never touches a baseball again. I'll stop now.

Seriously again, though, regarding the 787, thank goodness terrorist cells do not have many electrical engineers. I'd imagine they have tested these against pretty significant shock forces. It will be very interesting to find out what is the culprit, now reports indeed naming an external foreign supplier of parts for the cells. Wonder if the engineers can retrofit NiMH cell pack for the jets, probably not a simple replacement to design.
