7 Myths About The Challenger Disaster
Lester67 writes "James Oberg at MSNBC has put together an excellent recap of the 7 myths surrounding the Challenger shuttle disaster. I remember that day clearly, but as the author points out, I didn't see it live, nor did a large chunk of the people said they did (Myth #1). Although there are no surprises on the list, regression may have caused you to forget a few of them (#3)."
I remember clearly watching the events unfold in my second grade classroom (must have been the satelite feed mentioned). I think it was the most traumatic event up to that point in my life.
The librarian had rolled out one of the ubiquitous "TV + giant VCR" stands and parked it in the middle of the reading area. For a librarian that typically insisted on a completely quiet room, this was unusual. I suppose the novelty of the teacher going into space prompted her decision.
Anyway, that unusual situation was enough for me to watch the launch, motivated by the taboo feeling of watching TV in the otherwise serenely quiet library and being a bit of a space nut. Despite that and to corroborate the claim in the article, I was probably one of only a few people actually paying attention to it, as most other students were taking the situation as a license to talk to eachother.
I clearly remember watching it desintergate, fanning out into a cloud -- and my mind not being able to fully comprehend what was happening. I might have even vocalized, but I can only remember the visuals. It seemed to take forever for other people to catch on to what had happened.
Regarding exploded, I have to disagree. Cars don't explode in accidents, though they often get pretty badly mangled and have pieces break off. It's reasonable to say that a lot of things which aren't detonations are explosions... a pressurized cannister of gas say, if it has a structural failure... or a boiler. But Challenger wasn't pushed apart by any sort of internal force. It pitched up rapidly at twice the speed of sound, and like any airplane suddenly tragically flown out to several times its structural design margins, broke into pieces.
It's particularly hard to make this point as what people saw as an explosion... the fireball... in fact had minimal overpressure and thermal density, and essentially didn't damage either the pieces of the Shuttle (which had already broken up) or the solid boosters. People always think that the fireball caused, or somehow was related to, the deaths. It was completely unrelated. If the external tank had been filled with perfectly inert water, and the shuttle came up off the stack as it did, the breakup of Challenger and eventual deaths of the astronauts would have been exactly the same.
You may think it's nitpicking, but it often matters for people to understand exactly which part of something caused deaths or destruction. Katrina didn't devastate New Orleans because it was a Cat 5 storm; Katrina pulled in a water surge which damaged levees which flooded the city. If there had been no Katrina, and random liquefaction caused a levee failure on a clear day without a storm in sight, New Orleans would have been just as badly damaged. That's not true for a lot of surrounding areas though, where Katrina floodwaters from the storm surge did directly cause the damage, and the New Orleans levee breaks later were irellevant.
I'm designing manned spacecraft now, and the details of what can go wrong during launch, in space, and during reentry matter. There are a lot of things which can go wrong and may look spectacularly bad, but shouldn't kill the crew. I am more concerned about the ones which could kill the crew, some of which don't look all that dangerous to the naked eye. Soyuz 10's crew died because one small valve failed and let all the air out as the capsule was coming down. Columbia's crew died because small pieces of foam falling off tanks got to be routine, and eventually after 100 missions a big one fell off and hit probably the single worst place on the whole Orbiter.
Agreed, in this day and age of revisionist historians employed by our governments around the globe, who's sole job it is to re-write history in the favour of the encumbant politicions, it is VERY important that what actually happened during a pivotal event is recorded and re-told correctly. If we brush over the facts, how will we know how to stop it happening again ?
One of the positive things about the Internet, is it's ability to give everyone a voice. I still have enough faith in the world, that those who what to do the right thing easily outnumber those that dont. Concepts like Wikipedia help to preserve the real facts of events because so many people have a vested interest in keeping the articles they contribute to error-free. Information is power, and the governments of the world don't understand that they no longer control the information flow.
When something tragic happens the independent blogporters outnumber the employed reporters 10 to 1, agreggating those blogports will yield a more accurate and complete dissection of the event than any commercial newsfeeds can or want to provide.
Reading through the Myths in the article I was astounded under Myth #2 to discover that TV companies dubbed in an explosion sound! We can no longer trust what the news shows us.
Paranoid, me? Never.

What I really noticed about this article was the claim that some TV-companies added an explosion sound to the footage. Doctoring footage and images: I've seen so many examples of newspaper images that were so similar, I've often wondered if news agencies don't pull up photoshop to make the image a little more illustrative.
There always seems to be a russian woman walking past a huge poster of Putin, an iraqi woman walking past a huge poster of Saddam, a venezuelan woman walking past a huge picture of Chavez. And a picture of a white dove with a palestinian demonstration in the background. They are both in focus... how did the photographer get them to stand still? And I don't think you can trust that demonstrators really held up the posters they did. Far too often, it seems that the most prominent poster is held by someone who is not in the image. Remember the affair when a parody image of "Evil Ernie" appeared in an image of bin Laden? It was claimed that the demonstrator had done an image search on the net and accidentaly downloaded the parody image, but if he made that sign, wouldn't he have noticed that bizarre puppet in the backgound?! I think it more likely that someone at reuters or AP decided that the image wasn't illustrative enough, and did the negligent image search
So now I see a major news outlet claiming that such "illustrative" manipulation occurs, perhaps I'm not paranoid, after all.
