Challenger 25 Years Later 236
25 years ago, I peered inside through the playground window of my school. I was never particularly interested in being outside, and there was a shuttle launch on the library TV! The images of what I saw that day will stick with me forever. I didn't know what it really was I saw; I just made jokes. It's still how I deal. But I think I'm a bit wiser today, having maybe learned that the bleeding edge is sometimes literal. The technology we take for granted descends directly from the people willing to do what we never could. Thanks to the crew of Challenger,

I was also home sick that day, from first grade. I had become very interested in the space program and it was the first time I would see a shuttle launch on television. Actually, I don't recall seeing another until at least my teenage years. Watched on the television in my parents bedroom, and couldn't think of what to do when it exploded. I went downstairs and told my mother, and she in turn could not think of what to say back to me. It remains one of the most vivid memories of childhood.

As a seventeen-year-old kid, on July 16, 1969, I stood in the front yard of our rental home in Satellite Beach, Florida, and watched Apollo 11 take off for the Moon. It was THE high point of my life to that moment (although the lunar landing and historic first footstep replaced it as such four days later).
Flash forward to January 28, 1986, the day I began working for an audio-visual rental services company in Oakland, California. One of our routine tasks was to test equipment that had been rented out, to ensure that it worked properly before renting it out again. As the brand-new guy, I wanted to impress the boss with my willingness to work, so I started checking a bunch of gear that had been returned at closing time the previous day. Early on in the process, I tested a TV/monitor. I hooked up a VHS player, and that worked fine, and - going the extra mile here - I then hooked up a set of rabbit ears and checked the TV tuner.
The channel that came up was the local ABC affiliate, and I switched on the tuner just as their network announcer broke into Good Morning America to say, "We've just received this raw footage from Cape Canaveral." I watched the two minutes or so of launch footage, and saw for the first time the main fuel tank explode, and the solid fuel boosters' exhaust form the "devil horns" that would become so painfully familiar over the next few days. When the clip began to loop, and the announcer said, "We're not sure what we're seeing here," I muttered under my breath, "Well, I'm sure," and walked up to the front of the warehouse to the manager's office.
"Dan?" I said, "You probably want to see this. The space shuttle just blew up and killed everyone aboard."
Just barely more than 17 years later, on February 1, 2003, I stood in the East pasture of our little five-acre spread in Mariposa County, and watched the Columbia reenter the atmosphere above California. I wondered why I kept seeing pulses of light beneath its wings, but I was so happy to have the opportunity to view an actual shuttle reentry, that I pretty much dismissed it from my mind. Then I went back inside, posted an account of the experience to The Pigdog List, and went to bed (I'd just pulled an all-nighter working on a column for the late, great Boardwatch Magazine). When I woke up that afternoon, I checked my email, to learn ... well, we all know what I learned.
I spent the next ten days writing and recording a song [starkrealities.com] about the experience.
It's the second-saddest song I've every written.

Well, as usual, it's not nearly so simple as that.
The reality, that when the hardware decisions were being made - we had exactly zero flight experience with big monolithic solids and considerable flight experience with segmented solids. There's also the near impossibility of pouring the grain of a monolithic solid with sufficient consistency in performance, let alone matching two of them to required level of consistency. Then there's near impossibility of handling a million plus pounds worth of monolithic grain without flexing it and damaging the grain or the bond between the grain and the case.
So in reality, there was many reasons to prefer segmented boosters and no particular reason to prefer monolithic ones. (Which is why of the three bids submitted - only one was monolithic.)
You're also making the mistake of generalizing from the specific instance of the Shuttle to all segmented booster. The cause of the Challenger accident wasn't because the booster was segmented (we've flown many with zero problems), but because that particular joint design had a serious flaw in that it could not fully compensate for joint rotation.

Nesbitt's job, as the official public voice of NASA going out to the world during the launch, was to provide a running stream of information. The data came from what today seems like an amazingly primitive source — a single black and white, 9-inch monitor with lines of numbers and cryptic letters scrolling across constantly.
On a piece of paper in front of him Nesbitt also has the mission timeline, a listing of what was supposed to happen second-by-second with the shuttle. "About every 15 seconds there was a new milestone coming in on the timeline," he says.
Nesbitt was focused on the 9-inch computer screen in front of him, reading off numbers. The only actual visual of the launch he could see was a small television off to his left but he couldn't watch it and the computer so he wasn't looking at it.
Sitting next to him was the Navy flight surgeon for the launch, a young captain. "I heard her say 'What was that?' " Nesbitt remembers.
He finished reading the numbers off the screen and then looked over at the TV screen. "At that point there was just the trail of smoke. And I thought 'Oh, crap. There's something not right.' "
Note: Mission control may get a different video feed than the cross-cut CNN feed that we are all familiar with. Also, they are in a windowless concrete bunker a thousand miles away from the actual launch. The telemetry and the video feeds from the various tracking cameras are all they've got to go on.
There's a 15-second pause between his last words, "seven nautical miles," and the next ones. Neither Nesbitt nor anyone in the room knew what had happened. "I'm not hearing anyone in Mission Control saying 'The spacecraft just disintegrated.' No one's saying anything," he says.
Something was horribly wrong, he knew that. But he had no idea what it was, what had happened to the spacecraft and, most importantly, what had happened to the crew.
What Nesbitt did know was that it was his job to explain to the public what they were seeing on their TV screens. "I had this feeling 'I've got to comment on what's happening,' but I didn't have any information."
So the next words he uttered were the now famous quote: "Flight control is here looking very carefully at the situation, obviously a major malfunction."
Some at the time expressed surprise that his voice never changed during the next hour as the full extent of the tragedy became evident. But that wasn't Nesbitt's job: It was to give accurate information as quickly and smoothly as he could.
Nesbitt did an amazing job in my opinion. Sadly, sometimes no matter what you say it is the wrong thing to

When I've watched it in later years, though, I'm most struck by his professionalism and commitment to his job. This guy had to know his voice was being broadcast around the world, and that this was the most watched shuttle launch in years (possibly ever). He was probably himself just realizing from the data (I'm not sure he even had the video feed available to him at the time) that something horrible had just happened, and people he probably knew and worked with had likely just died. Through all that, he kept a measured tone and suppressed whatever emotion he might have been feeling. His calm monotone and understated assessment of the situation was the perfect backdrop to the utter shock everyone was feeling at that moment. Having that guy panic or lose his shit would have made the whole thing much much worse.

I was in college, working in the robotics lab. Within a few minutes there was a lot of speculation flying around Usenet. I wonder now whether any of it was on the right track.

(too bad the "had exploded" was being reinforced almost immediately; what looked like an explosion, was actually mostly burning of dumped fuel _behind_ the Shuttle - which was disintegrated mostly via aerodynamic forces)

What? The o-ring on the SRB failed, causing hot exhaust gasses to blowtorch directly onto -- and then into -- the fuel tank. The tank (and fuel) exploded. The orbiter was half blown apart from the blast and the rest disintegrated due to aerodynamic forces. The SRBs went off on their separate ways.
I guess you could say that the orbiter itself didn't explode, but at that point in time the "shuttle", the Space Transportation System, consisted of the orbiter, the main fuel tank, and the two SRBs. And the STS mo

The only connection here is that there were two accidents involving a Shuttle.

The guy saying that wasn't watching the shuttle as you were, he was watching a telemetry readout. He had no idea what actually had happened, all he had was "WTF? I just lost my telemetry.".

Bullshit. Engineers are people. People make mistakes. Five people can take the same set of data, and each draw different conclusions.
An engineer can say, "This is a risk. Don't do it." Another can say, "It's a risk, but it's an acceptable one. The probability of a failure is low. Launch it."
Someone has to make a decision. Sometimes that person is wrong. But all too often we take the stance that ANY potential risk, however unlikely, is unacceptable.
You know driving is a risk, but you do it. You know that tex
