In the second pic you get a good idea how thin the carbon skin is on this airframe.

Just called Qatar Airways and asked the agent to book me on the Dreamliner from DXB to DOH, and back.

Problem is they cant guarantee an airframe switch at the last moment. Hope fully one of the legs will be the Dreamliner if not both.

i flew jetstar recently with their 787 and the best thing about it was quietness, spaciousness, efficiency, and a very smooth ride. the landing was best!

This is what JAL has said about the incident on their website where they have posted all the delays after the grounding.

Quote:
Flight: JAL707 Tokyo (Narita) - Bangkok

- A maintenance personnel in the cockpit found that the white smoke was wafting outside of the window and that the message which indicated the possibility of main battery system failure was displayed on the cockpit display during departure preparation.

- The inspection of the battery case inside the battery enclosure revealed that the safety pressure relief valve (which opens in case that the cell inside pressure rises) of one cell of the eight cells opened.

- JAL707 departed by another Boeing 787 almost on time.

This might actually be a very positive incident. The cause of the incidents last year was never found, now that the damage is very limited they might find what was actually wrong with the batteries. And it also looks like Boeing's solution worked, the problem was contained to 1 cell, it didn't spread to the other cells in the battery.

Hopefully this incident will provide all the information to make the batteries better.

unfortunately the media will blow this all out of proportion. Boeing's stock is down 2% after the news broke. Plus on Thursday will be the one year anniversary of the 787 grounding. Hopefully this time of year does not curse the 787 with problems every time it rolls around.

I still have my doubts about the fix, the overheating means there is a problem they can't find, as you said let's hope this will shed more light into the matter.

There was no thermal runaway so the fix has worked as designed.

Lithium ion batteries will fail from time to time and nobody can prevent that from happening.

Here is an article that ATW has on their website.

Parked JAL 787 has ‘main battery failure’; ‘white smoke’ reported

Japan Airlines (JAL) said a “main battery failure occurred” on one of its Boeing 787-8s parked at Tokyo Narita Airport on Tuesday. The airline reported that “white smoke” was seen in the incident, which resulted in no injuries.

JAL said one of its maintenance personnel was checking the parked aircraft prior to a planned departure to Bangkok. There were no passengers on board the aircraft at the time. “A maintenance personnel in the cockpit found that the white smoke was wafting outside of the window and that the message which indicated the possibility of main battery system failure was displayed on the cockpit display during departure preparation,” JAL said in a statement.

It is unclear what caused the incident. JAL passengers were flown to Bangkok on another 787.

“We are aware of the 787 issue that occurred Tuesday afternoon at Narita, which appears to have involved the venting of a single battery cell,” Boeing said in an emailed statement. “The issue occurred during scheduled maintenance activities with no passengers on board. The improvements made to the 787 battery system last year appear to have worked as designed. We sincerely regret any impact caused to Japan Airlines and are working with them to return this airplane to service.”

The latest JAL 787 battery incident occurred more than seven months after JAL resumed 787 flying following a global grounding of the Dreamliner fleet prompted in large part by a battery fire aboard a parked JAL 787 at Boston Logan Airport on Jan. 7, 2013. Boeing last year designed a comprehensive fix for the 787’s two high-powered lithium ion batteries, used for the aircraft’s main battery and auxiliary power unit (APU), which was approved by FAA and enabled the resumption of 787 commercial flights following a grounding that lasted more than three months.

Didn't Boeing replace all the batteries with old-tech batteries? Or was that just for the newer builds?

They didn't, they designed a new airtight fireproof encasement around the Li-Ion batteries with a special valve to vent out any heat when an event like this happens. They also put more space between the cells that make up the battery.

Airbus changed the initial design of the A350 to traditional batteries, but they will replace them with Li-Ion batteries in the future.
