  2. Very questionable claims! on 7 Myths About The Challenger Disaster · · Score: 1, Interesting
    > 1. Few people actually saw the Challenger tragedy unfold live on television.

    So? What difference does a minute or three make?

    2. The shuttle did not explode in the common definition of that word.

    No, it *did* explode in the common definition, as in boom, major disassembly. It did not explode in one specific, technical way. There was no bag of TNT on board. There was the equivalent of many tons of TNT just a few feet away. Big diff? I don't think so.

    3. The flight, and the astronauts' lives, did not end at that point, 73 seconds after launch.

    Well, effectively, they did. There was nothing that could be done at that point to save them. Also IIRC the only clue that a few were concious was that two of the emergency airpacks were found turned on. Not exactly uncontrovertible evidence.

    4. The design of the booster, while possessing flaws subject to improvement, was neither especially dangerous if operated properly, nor the result of political interference.

    Totally wrong. There were several previous documented cases of the O-rings burning part way through. Feynman's report clarifies the severe nature of this problem. If you manage to walk across the freeway blindfolded 66 times, does that certify the action as safe? Nope. The political angle is not documentable either way. But one might guess if the president is scheduled to talk to the astronauts during the state of the union address, there's some pressure there to launch.

    5. Replacement of the original asbestos-bearing putty in the booster seals was unrelated to the failure.

    Well, true in the sense that the whole basic design was foobar. But "unrelated" is a value judgement, one unlikely to be categorically false.

    6. There were pressures on the flight schedule, but none of any recognizable political origin.

    Yep, we went over that already. You expect to find a written memo on this?

    7. Claims that the disaster was the unavoidable price to be paid for pioneering a new frontier were self-serving rationalizations on the part of those responsible for incompetent engineering management -- the disaster should have been avoidable.

    Wishful thinking, and doesnt correspond with history. There's no way any engineer could get the shuttle grounded and a major subsystem completely redesigned just on a hunch. In the real world flaws often go unresolved until somebody dies. See: Pinto gas tank, Ford ABS switch, Dodge ball joints, Vioxx, thalidomide, radium drinks, smoking, children's air bags, and probably many more.

    It matters not one whit whether a patent has a "mistake" in it. Think of the two possibilities:

      • The person is the patent holder, he can do nothing, or file a correction. Big whoop.

      • It's somebody else, someone interested in breakng the patent. This gives them one more arrow in their quiver.

    For those of you puzzled by this story, you should be, as it's basically bogus.

    They're talking about inductive heating, which is a bit worrisome: It involves having a kilowatt or so of 13.56 MHz radio frequency energy beamin up at the cooking implement.

    The pot can't be just any pot-- it has to hit a certain electromagnetic sweet spot, as to absorb the radio waves, and not reflect them all over the place.

    this usually implies it has to be made of somewhat resistive and lossy material-- iron is a good choice.

    Unfortunately materials that are resistive electrically are usually resistive, thermally too. So instead of getting a nice even heat, the pan is likely to have hot spots.

    Ergo the pans really could use some sort of sensor to feed back to the stove some info about how the pan is heating. As to not have some cool spots while nearby the pan is melting through.

    So this isnt so much a wonderful added feature, as a partial kludge to compensate for the basic foibles of the whole scheme.

    I'm going to be patient here, because we haev an obvious miscommunication in part. I repeatedly mentioned the www.fas.org web site, with its 2 and 1 meter resolution images as my source of information. Where you got google earth as my reference is beyond me.

    Now about those cracks. Let me refresh your memory:

    • High-performance airplanes need to have thin wings.
    • Thin wings and tricycle landing gear imply landing gear and tires in the wings.
    • That implies thin, flat, smallish tires.
    • The thinner and smaller the tire, the more internal pressure the tire must have to support the weight of the plane.
    • So we're talking rock-hard tires, inflated to HUNDREDS of PSI. With little flex distance in the sidewalls.
    • That setup requires a VERY SMOOTH runway, with like, no irregularities larger than about 1 centimeter.
    • If you can see a crack from an aerial photo-it's likely to be a whole lot more than 1 cm.
    • Remember the Concorde tire that ran over a relatively small piece of metal? Boom. Your car tire would have no problem deforming and flowing over that kind of obstacle. High-pressure tires don't have the same ability. KabBoom!

    A few more refreshers:

    • Every see a runway or highway being built? What;'s the first thing they do? Build a base.
    • That means several feet of gravel.
    • But out in the boondocks, in an area that has never been scoured by glaciers, and has no flowing rivers, and instead has been subject to eons of slow erosion, resulting in a surface coverd by hundreds of feet of fine sediment, gravel just isnt available, like not for hundreds of miles.
    • And at a secret installation, it would not be prudent to have hundreds of 18-wheel dumptrucks going hundreds of miles down the interstate and turning off down a cowpath for another 30 miles.
    • And the govt and military moves people around every few years, so nobody cares much about building things that last.
    • So it's quite likely they didnt lay down ANY base below the runway.
    • After a few years of spring rains, which turn the lakebed to cream-of-mushroom soup for a few months, funny, the concrete starts to crack.
    • Ergo, it's no longer a runway. At least not for anything delicate, or untested at high gross weights, or often having to land unexpectedly with high fuel loads.

    Not to put too fine a point on it, but : If you can see cracks from the air, it isn't a runway for experimental aircraft.

    It might be passable for aircraft designed for rough landings, like a C-130, C-5A, Twin Otter. Not for a B-58, U-2, XB-70.
