    It's easy to second guess NASA's decision making but, when you are in that moment, it's a hard trigger to pull. I've no doubt that engineers were concerned about the integrity of the O-ring seal. However, when they launched, they were within published spec.
    The spec said "NO EROSION OF THE PRIMARY O-RING". But they continued to fly despite the fact that said erosion was ocurring.

    Ultimately it was the erosion that was the problem - the cold made what happened (a full burn-through) more likely, but it could have happened at much balmier temps as well. The real cause of the accident is yet another step back from the obvious - the joint rotation which had been occurring, and seen as a potential problem, since very early in the program.

    In that situation, it becomes your (expert) opinion vs. established data. You might be right, but it's hard to push through.
    The dilemma that management faced was this; the engineers (the experts) has been telling them it was safe to fly, despite erosion problems, while they (the experts) sought a fix. Then the experts suddenly reversed themselves on the eve of the launch and starting claiming that it was not in fact safe to fly - but they couldn't produce an engineering justification for that claim.

    Personally, I believe that the origin of 'put your management hat on'; it was shorthand for "look at it from my point of view [as a manager], would you trust a bunch of guys who can't get their stories straight, or back their stories up with documentation?".

    There were grand plans for NASA that reached beyond Apollo and the Moon. Lunar Bases, Manned Missions to Mars, Space Stations, Reuseable Shuttles, the whole shebang. Unfortunatly at the same time, we were stuck at a horrible point in our history.
    I wouldn't go so far as to call them 'plans'... Those were the things that NASA hoped to convince Congress to fund, nothing more. Despite the impression the NASA PR machine attempted to create (and the media conspired to help them, to the point that today it's difficult to seperate fact from fiction), they were at best what today would be called a pre-alpha demo.
    Unfortunatly at the same time, we were stuck at a horrible point in our history. Nixon was taking a savage (and deserved) beating over Vietnam. The country had little faith in its government, and just a few years later we were hit with an Oil Embargo that did a nice job of slamming our economy.

    Congress started looking for places to cut the budget and, just like in Civ 3, Science took the hit. NASA's budget took a massive beating over the next few Fiscal years.

    The reality is that the first big cuts were in fiscal year 67 - two years before Nixon even took office. The cuts after that were ongoing and much less severe.
    They were thrown a bone and allowed to put together Skylab on a shoestring budget, then (late 70's early 80's) were saddled with the proverbial "good idea at the time" of the Shuttle program.
    NASA saddled *themselves* with the Shuttle. Development on the Shuttle started in earnest about 1967. NASA was asked by the Nixon Administration in 1971 for a post Apollo plan, and NASA presented an ambitious scheme involving Shuttles, moonbases, space stations, Saturn V's, nuclear powered boosters, etc... etc... The total cost would have been about 5-8 times that of the Apollo program. (Note carefully the dates - NASA proposed this in spite of the fact that their budget has been steadily cut for four years!) The Administration (and Congress) took one look at this plan, considered NASA's (even at that early date) infamous ability to properly estimate and susequently control costs - and tossed it back into NASA's face.

    Despite the resulting political train wreck, NASA convinced themselves that the blank checks would soon be flowing again - and *they chose to develop the Shuttle* on the theory that since it was the basis for the whole system, they needed to get a head start for when those checks came.

    That doesn't mean that there are not ways of terminating the thrust of a solid with reasonable safety - there are. Shuttle doesn't use them because the parallel staging system it uses renders the use of those methods problematic.

This was one of the things that lead to the Apollo 1 accident, very few 'lessons learned' could be implemented - because they hadn't been learned yet.

    What annoys me is the continued myths about the engineers. (And JimO knows better - he's participated in the debates over their roles, but instead he goes for the sound bite.)

    The engineers approved flights despite evidence of O-ring erosion (even though the specs said no erosion). The engineers approved flights when the temperature at launch time hovered near or below the lowest temperature allowed by spec. Thus when managment questioned them about their reticence over the 51-L launch - they hemmed, and hawed, and did everything to avoid making a clear and straightforward call.

    And imposing a flawed managerial direction by applying social pressures (bullying/bamboozling) to brush dissenters under the carpet just made it worse. All highly unprofessional.
    Unfortunately, it's not as simply as them being bullied and bamboozled. The engineers insisted that the launch was potentially unsafe, and when the managers asked for evidence - the engineers were unable (unwilling?) to make their case clear. *That* is highly unprofessional - making a claim (this launch is unsafe), and then failing to back it up.

    In the end, when the engineers were polled for their reccomendation, not one stood up and called for the launch to be halted. Not one.

    The problem with that theory is reality. From aft strut failure to total breakup of the shuttle was less than two seconds - not nearly enough time to realize something was wrong, frame a sentence, and then key the mike. There were no possible instrument indications in the cockpit to show the impending accident and no significant movement of the cabin prior to breakup.
    It wasn't until much later (memory's admittedly hazy on the timeframe), as the investigation into the disaster progressed, that it was reported that the crew had survived the booster failure, and possibly even the whole way back down, and that news was generally buried and ignored, because people really didn't want to hear that.

    Materials scientists tend to know little about how composite materials like the RCC panels age, especially in the harsh environment they had to endure -- radiation, violent temperature swings, et cetera -- and especially over the 20 years or so between Columbia's fabrication and the accident.
    Read the CAIB report - the RCC panels were routinely inspected and replaced.
    Here for example is a story about some of the problems the USAF is running into now with the F-15 wing, which is composite and approaching 20 years old in many aircraft, e.g. the linked article notes an F-15 coming apart midflight in 2003 because of a sudden failure of the wing, and yet routine inspections every 200 hours had shown no signs of incipient failure.
    Read your own linked article. What failed was the honeycomb inside the wing (not the composite material), which can't be reliably inspected. (I.E. the failure was a material that isn't in the Shuttle's RCC panels and can't reliably be inspected the way the RCC panels can.)
    If Columbia's accident was the result of this kind of failure,
    Since it wasn't... (The CAIB ruled out RCC failure due to aging.)
    Indeed, I think one of the lessons of Columbia should probably be that these things still happen, that materials and systems can fail in totally unforeseen ways, even with the best engineering talent and the best management will in the world.
    Right. Except for the mountains of evidence that the foam shedding was ongoing and causing damage *and* the mountains of evidence that engineers and management chose to turn a blind eye to those facts...

We can ask the Game Librarian whether placing games in the library is a positive example for society. We can ask the Game Librarian whether games in the library leave it a better place (not a 'cooler' place, not a 'more relevant' place, but a better place) than it was without games.
