  2. It's time to ground the entire rotting piece of junk.


  3. You're a goddamned retard. You're grounded, boy.
  4. Expect to find a whole lot of anti-Russian stuff in the news.
    This is because the US was humiliated by Putin as regardin gIran.

    How many starts were made by Russia because the foam build shuttle failed?

    I remember all those video clips of Bill Shepherd, the first Station
    commander, floating here and there with at least one roll of duct tape
    wired to his belt. :)

    We'll have to kill more astronauts, perhaps the entire station's crew,
    before that happens.

    Are you claiming the article is untrue? Or that it should be supressed
    for political reasons? Or that the IEEE published it to humiliate

    Whoever packed a roll of it on Apollo 13 deserves a Nobel
    Prize. ;-)

    I was in a plane one day at the terminal, and there was a plane next to me.
    I was looking at the wire comming out of a door, duct tapped to the fuselage.
    Seemed like it went between two doors. I kept wondering about that.

    Not sure what he's driving at - but I am dismayed at the anti-Russian
    closing. Let's face it folks, our (US) space program has killed a lot
    more people lately than the Russians'. Space research isn't safe, and
    mistakes will be made. And they will cost lives.

    It's easy to stand on the ground in Houston and make wise noises after
    the fact. It's much harder to build something and anticipate *every*
    mode of failure. Heck, I've been designing things for 20 years and have
    probably never anticipated every single point of failure ahead of time.
  11. I am considering the possibility Winfield posted it for political reasons.
    Sure the article itself is highly anti-Russian.
    You guys got to get rid of Bush, he makes the US look like an idiot.
    (rest see my postings in us.politcs, this is not the place, my name is not Tom Jimpson
    or something LOL).

    I've always been amused at the novel failure mechanisms I didn't
    anticipate... my most famous was applying short-circuit protection to
    an output stage only to have the driver fail from uncontrolled current

  14. My best mistake was designing a radio with BITE (built in test
    equipment). The idea was that failure was inevitable and that BITE
    would expedite repairs and therefore improve overall uptime. The
    problem was that BITE was an afterthought and was done in the
    traditional unplanned last minute rush. The radio worked just fine,
    but the BITE sections were constantly failing.

    Long ago, I lived with a ladyfriend that was aspiring to become a
    medical doctor. Our philosophies were radically different. I was
    into maximizing the number of trial and error mistakes (also known as
    try, test, and tweak). She was into never making a mistake. I
    learned quite a bit about approaching problem solving, diagnostics,
    and "repairs" from her perspective. Today, it's called defensive
    medicine. Fortunately, it hasn't hit electronics quite yet, except in
    the space program.

    I found the IEEE Spectrum article interesting in that it demonstrated
    that assigning the blame really is the first step in solving a
    problem. In most bureaucratic organizations, this initial step is
    vital. I've worked for companies where a culprit must be found before
    any problem can be fixed. I also found it interesting that when it
    finally came down to the actual troubleshooting, visual inspection
    again showed what was not obvious to the test equipment. I've lost
    count of how many times just looking at the problem showed something
    that was not anticipated. My favorite was a malfunctioning remote
    weather station, that was inadvertently converted into a bee hive.
    None of the specs mentioned anything about making it bee proof.
  15. Use it for ASAT target practice.

    We had a series of unexplained failures in our DC motors. The seals
    (rubber plugs that keep the water out) kept failing. These motors are
    used outside in remote agricultural areas.

    We went through all sorts of testing, back and forth with the
    manufacturer, and everyone was at a loss why these seals would fall out
    of the motors, usually within days after they were put in service. No
    amount of yard testing could make these plugs fall out.

    Then one day a sharp eyed field hand noticed the cows were eating the
  17. Strange, I didn't see the article as anti-Russian (as for
    the administrators, they aren't so different from ours).

    But I did see it as pro duct tape. As it happens, duct
    tape is an important part of the shuttle missions, since
    our astronauts use it to create impromtu work areas, tape
    laptop computers to the walls, etc. Very important stuff,
    but something of a secret. That's what I meant by "again",
    referring to our own heavy use in space.
    Well, I do agree with that, as y'all know.
  18. Said with tongue firmly in cheek, I'm sure. ;-)

    In organizations heavily invested in accident analysis, troubleshooting
    and life safety (FAA/NTSB, NFPA, etc.) the policy is to defer assigning
    the blame until after the forensics is done. In many cases, penalties
    are forgiven permanently in order to encourage open exchanges of
    information necessary to support investigations.

    In my experience, it is these situations that cause the incompetents to
    surface and insist upon blame assignment up front. Its a means of
    protecting a reputation when they know that the odds are high that the
    sh*t will end up in their lap in the end. Get it put in the meeting
    minutes up front and if the issue ever comes back at them, they can
    brush it aside by demanding that closed items not be revisited. The best
    defense is often a good offense.

    Competent individuals can survive a few screw-ups in their careers and
    will in fact learn from them. Its called lessons learned and it
    demonstrates an individuals' ability to improve.
    This illustrates one of the primary arguments for manned space missions.
    In spite of the additional expenses involved, having people available to
    pop a cover off of something and look is the only way to catch all the
    stuff that can't be handled remotely.

    Win, You're not qualified to use the phrase "y'all"... that is by
    birthright only ;-)
