From a sublime “Dreamliner” to the ridiculous

October 10, 2013

Nightmares (for Boeing) are made of this:

ReutersJapan Airlines Co was forced to turn around its Tokyo-bound flight from Moscow on Thursday due to a problem in the Boeing 787 jet’s lavatory, a spokesman for the Japanese carrier said. … 

JAL spokesman Takuya Shimoguchi said the toilet malfunction on the flight from Moscow was likely caused by an electronic glitch. The airline was working on repairs on the ground, he added.

The flight, carrying 141 passengers, departed Moscow on Wednesday evening and returned after about five hours, he said.

Shares in JAL, which made headlines this week by signing with Boeing rival Airbus for the next generation of long-haul jets, were up 2.1 percent on Thursday morning, outperforming the broader market.

Updated 10th October:


Japan Airlines (JAL) says it has turned around two of its Boeing 787 Dreamliner aircraft during flights due to technical problems.

On one plane one of the two anti-ice systems, which prevent ice building up around the engine, failed.

Meanwhile, an electrical glitch made six toilets unusable on another flight.

These are the latest technical issues to hit the Dreamliner, which saw the entire fleet being grounded earlier this year following battery problems.

A weekly post on things that were interesting or which I would have liked to have blogged about …….

Science and Behaviour

The Fonseca Bust

Hair-dos and archaeology come together in an intriguing article in the Wall Street Journal which shows that there is a logic to hair styling.

MIT research suggests that India joined with Asia 10 million years later than previously thought while Caltech research indicates that that iron melts at higher temperatures than has been reported in the past and that the earth’s core more be a trifle warmer than has been assumed before.

257,885,1611, which is also the 48th  Mersenne prime, was discovered on the computer of Dr. Curtis Cooper, a professor at the University of Central Missouri.

Global warming hard-liners are having to accept that the world isn’t warming as quickly as their catastrophe theories suggest. But they are not yet giving up on their religious beliefs about the anthropogenic causes of warming. But some more of the alarmism around global warming has to be recanted or at least toned down as new studies show that the Amazon rain forest is far more resilient to climate change than the doomsayers would have us believe.  Back in 1975 when the catastrophe theory of the day was the imminent cooling of the world, there were suggestions that the Arctic should be melted to try to get the world to warm up!!

Apparently certain certain volatile organic gases can promote cloud formation in a way  never considered before by atmospheric scientists. So much for “settled” climate science.

Pain and itching are both sensations which have a protective purpose and are linked to survival. Itching warns of the presence of irritants and it may be that there are a specific set of nerve cells that signal itch but not pain.

Flocking starlings strike an optimal balance between the work of responding to social cues from their neighbors and the need to conserve energy. They do this by coordinating with their seven nearest neighbors and form their characteristic flocks with the least effort.

Sweden is not immune to discrimination against job-seekers who have “foreign” names.

Amherst College seems to be taking sexual violence on campus seriously……

Engineering and Technology

The oil shale boom is having unexpected benefits even for rural banking in addition to changing the face of energy supplies.

The origin of the battery fire that occurred on a Japan Airlines (JAL) 787 at Boston Logan Airport in January has been identified as a single cell in a lithium-ion battery cell. Now the causes of the initiating short-circuit have to be found.

Meanwhile, Boeing has started telling its customers to expect serious delivery delays for the Boeing 787 as far out as this summer.

Bad Science

A mediocre academic, Brett Mills, seeks publicity by claiming that David Attenborough is minimising the prevalence of gay animals!

Earthworms are long revered for their beneficial role in soil fertility, but with the good comes the bad: they also increase greenhouse gas emissions from soils.

The Japanese Education Ministry is eyeing stricter penalties for researchers who misuse public research funds or commit fraud.

Last week, a California woman filed a lawsuit against Pfizer, the maker of Zoloft, alleging that Zoloft works no better than placebo, that Pfizer knew it, and that the company has run a systematic campaign to deceive doctors and the public in order to continue selling the drug.


Dreamliner still having electrical teething problems as fire breaks out in empty JAL aircraft

January 8, 2013

UPDATE! 9th January

(Reuters) – Boeing Co’s 787 Dreamliner jet suffered a third mishap in as many days on Wednesday, heightening safety concerns after a string of setbacks for the new aircraft.


Some 800 Boeing Dreamliners have been ordered so far and the first Dreamliner entered commercial operation with ANA in late 2011. That was about 3 years later than planned following a string of production issues. The Dreamliner has had a number of teething problems – mainly with electrical systems. Qatar Airways had to correct electrical faults and a United Air flight had to make an emergency landing  because of power failure. The FAA had also found some faults with the installation of the fuel system and had called for all Dreamliners to be inspected. Now a JAL aircraft has had a battery fire after landing at Boston – but there were no passengers on board at the time.

But the problems experienced so far do not seem to be anything extraordinary compared  to what could be expected with a brand new aircraft. The Dreamliner has not – unlike the Airbus A380 – experienced any serious engine problems so far. Another year of flying will probably see all the initial bugs ironed out. Then it will probably take another 5 or 6 years before any generic design issues – due to materials choices for example – start showing up.

NY Times:  A Boeing 787 Dreamliner aircraft with no passengers on board caught fire at Logan International Airport in Boston on Monday when a battery in its auxiliary electrical system exploded, officials said.

A mechanic inspecting the Japan Airlines jet discovered smoke in the cockpit while performing a routine postflight inspection and reported it to airport authorities around 10:30 a.m. Eastern time, said Bob Donahue, the fire chief of the Massachusetts Port Authority.

A fire crew responded and determined that a battery used to power the plane’s electrical systems when the engines are not running had exploded, Chief Donahue said. The mechanic was the only person on board the plane when the smoke was discovered, and no one was hurt by the fire, he added. ….

…… The 787 relies heavily on electrical power to drive onboard systems that in other jet models are run by air pressure generated by the engines. It also experienced electrical problems during testing that prompted a redesign.

The Dreamliner has experienced a string of problems with its electrical systems in recent weeks. On Dec. 4, a United Airlines flight from Houston to Newark made an emergency landing after it appeared that one of its power generators had failed.

On Dec. 13, Qatar Airways said it had grounded one of its three 787 jets because of the same problem United experienced. On Dec. 17, United said that a second 787 in its fleet had developed electrical problems.
