  1. Does anyone have a pointer to a good technical discussion of the
    Dreamliner batteries?
  2. Thanks for the suggestions, but I was hoping for something beyond the
    front-page ignorance.

    What is not new is the corporate incentive to pass tests without any
    problems such as added cost or schedule delays. The most valuable
    employee a big company can have is the engineer who asks "But what
  3. Yeah, but this plan has been cancelled or so I heard. They'd have to get rid
    of a vast number of exhausted batteries. This batteries could easily be
    dropped in the ocean when they fly above it but it seems Green Peeche
    protested and threatened to boycot the planes.

    that's probably a good thing, their job it to find reasons for
    and try to prevent them from happening again

    remember one of the investigators on "air crash investigations"
    "pilots get too much of the glory and but also too much of the
    clearly something went wrong, Boeing estimated less than one event
    per 10million flight hours, now they've had two in fewer than 100,000

    NTSB is conducting the investigation, not FAA. FAA has been put on the spot by NTSB and will eventually have to explain their approval of the Boeing testing. FAA and Boeing are both in the same pot of hot water.

    Yeah, since they are in the Yuasa aviation high reliability line, they would never have thought about the altitude thing...

    Didn't the US government loan them (taxpayer) money to buy the planes in the first place? They'll just put an interest free moratorium on the payment schedule.

    Anything we do , to do with aircraft electronics is subject to strenuous
    vibration and temperature cycling over a period of days. Mind you, it's 99%
    Military... but I would have thought the same things/rules apply to civil
    aircraft ?
    I would have thought tests would be at least as stringent- many lives are at
  9. (Shrug) Give them 19,900,000 more flight hours and they could still
    meet spec!

    To use a TLJ line from MIB "Try it" -K

    I think you are a goddamned idiot who has zero capacity to see the
    bigger picture in anything.

    Try landing a 100% full to capacity craft of ANY design sans power.

    It ain't fun, and you better be the best fucking physicist/pilot there
    is. And think on your feet real fast.

    Go back to your Balsa wood, rubber band powered gliders, child.

    You are a true idiot. Why don't you go there, if you are so hep on a
    communist regime that got EVERYTHING handed to it or they stole it.
    And they still do.

    They've also got the tanker boondoggle to tide them over. $52bn is a
    considerably subsidy.

    "Unethical conduct
    In May 2003, the U.S. Air Force announced it would lease 100 KC-767 tankersto replace the oldest 136 of its KC-135s. In November 2003, responding to critics who argued that the lease was more expensive than an outright purchase, the DoD announced a revised lease of 20 aircraft and purchase of 80. In December 2003, the Pentagon announced the project was to be frozen while an investigation of allegations of corruption by one of its former procurement staffers, Darleen Druyun (who began employment at Boeing in January) was begun. The fallout of this resulted in the resignation of Boeing CEO Philip M. Condit and the termination of CFO Michael M. Sears.[35] Harry Stonecipher, former McDonnell Douglas CEO and Boeing COO, replaced Condit on an interim basis. Druyun pleaded guilty to inflating the price of the contract to favor her future employer and to passing information on the competing Airbus A330 MRTT bid. In October 2004, she received a jail sentence for corruption.[citation needed]

    In March 2005, the Boeing board forced President and CEO Harry Stonecipher to resign. Boeing said an internal investigation revealed a "consensual" relationship between Stonecipher and a female executive that was "inconsistent with Boeing's Code of Conduct" and "would impair his ability to lead the company".[36] James A. Bell served as interim CEO (in addition to his normal duties as Boeing's CFO) until the appointment of Jim McNerney as the new Chairman, President, and CEO on June 30, 2005."

    Smaller than a truck battery I'll buy that.

    Is the scale in that photo centimetres and inches ?
  19. Jasen Betts

    Jasen Betts Guest

    I found this photo with an engineer

    the one with the scale was like this.

    here is a "before" image:

    10" x 7" x 12"
    253mm 178mm 305mm

    car battery:

    230mm x 173mm x 134mm

    so it's over twice the volume of that one
