Challenger Tragedy - In Depth, and Deeply Felt

Patchw0rk F0g writes "On this, the anniversary of the Challenger disaster, Jay Barbree has a moving and in-depth piece on this international disaster." From the article: "During several earlier shuttle missions, disaster did everything it could to crawl into the shuttle launch system and turn it into tumbling flaming wreckage. The primary O-rings on those flights suffered severe erosion from superheated gases, sometimes accompanied by lesser erosion. And the erosion had occurred after launch temperatures much higher than on this freezing Florida day -- 53 degrees was the lowest launch-time temperature up to that time. The booster engineers felt helpless. For months, they had been studying the O-ring seal problem. They knew a disaster was coming, but no one stepped forward and said, 'Stop this train until it's fixed.'"

"international disaster"

[orangeguru]

Aha. Very international.

I remember exactly where I was...

[voss]

I was in class, when they announced it over the intercom. For the Generation X'ers this was our 9/11. The moment that replayed in our minds for years to come.

I suppose I'll remember those last words

"Go at throttle up"

Re:I remember exactly where I was...

[mtaht]

I was sitting at the top of a flight of stairs when I saw Challenger explode. I slowly slid down the stairs, and then watched the video again and again, again, until every frame was burned into my memory.

And although the last words on the black box might have been "uh, oh", the last words heard over the air were: "Go for 104 percent".

Then there was this horrible "Snick!" as the radio went dead.

There's a sample of the last sounds from the shuttle on this song.

I saw Richard Feynman's eloquent demonstration of why the boosters failed, and watched him be ignored by the other members of the commission. I learned of the group of engineers at Thiokol that were overrulled by their management to give the "Go" to this mission...

I visualize these moments in time every time I am given management directives that attempt to contravene physical law, and to this day I stay true to my profession as an engineer, and do the right thing by the physics. It's the only way I can sleep at night.

Still, I remain haunted.

Re:Motivation

[Anonymous Coward]

Are you forgetting that NASA, and Morton Thiokol management is solely responsible for the disaster, the engineers protested the launch.

It bears repeating.

[Corf]

Oh! I have slipped the surly bonds of Earth
And danced the skies on laughter-silvered wings;
Sunward I've climbed, and joined the tumbling mirth
of sun-split clouds, --and done a hundred things
You have not dreamed of--wheeled and soared and swung
High in the sunlit silence. Hov'ring there,
I've chased the shouting wind along, and flung
My eager craft through footless halls of air....

Up, up the long, delirious, burning blue
I've topped the wind-swept heights with easy grace
Where never lark nor even eagle flew--
And, while with silent lifting mind I've trod
The high untrespassed sanctity of space,
Put out my hand, and touched the face of God.

Re:Motivation

[pallmall1]

Obviously this wasn't a big enough motivation and it should be a wake up call for anyone who trusts that a contractor or engineer will tell you that there is something wrong with a product on their own.

Spoken like a true non-engineer. It was at the urging of Nasa officials that the launch was approved to take place. Here's a quote from the Nasa website relating the facts that you have conveniently overlooked in your rush to condemn engineers and manufacturers:

However, in a closed meeting at the Kennedy Space Center on February 14, Commission members were "visibly disturbed" to learn that engineers from the firm that manufactured the SRM, Morton Thiokol Inc., had the night before recommended against launching Challenger in the cold temperatures predicted for the next morning; that their managers, at the apparent urging of NASA officials from the Marshall Space Flight Center, had overruled their recommendation; and that more senior NASA managers responsible for the launch commit decision were unaware of this contentious interaction. --bold added

There's nothing insightful about the parent post, except for the insight gained into the readiness of some to unfairly accuse an entire profession they know nothing about of what basically amounts to murder. I'd like to know what the parent poster's motivations are, other than to try to sound cool on slashdot.

"tragedy"

[bcrowell]

"Tragedy" is one of those words that gets thrown around too lightly. These were people who knowingly took a risk in order to do something they believed in. They wound up losing the bet, and getting killed. That's not a tragedy. A tragedy is Romeo and Juliet, or a 10-year-old factory worker in Thailand getting killed while working to pay for medicine for his sick mother. A tragedy is not astronauts getting killed in an explosion, or mountain climbers getting killed by bad weather, or a volunteer soldier getting killed in a war he believed in.

Re:"tragedy"

[pjt48108]

You are correct, even though people are flaming you. 'Tragedy' IS a word too freely used, as is 'hero.'

You correctly note that they were aware of the risks, they took the risks, and lost. It's not technically 'tragic' or 'tragedy,' but that doesn't at all dismiss the deeply sad, unfortunate nature of the accident, despite the binary view some are ascribing to your comments.

The accident itself is just one in a larger series of events which might collectively be considered 'tragic." As someone noted in comments, there is usually a tragic flaw--such as hubris--giving rise to the tragic events, collectively known in literature as 'tragedy.' In this case, the tragedy is the larger story of humans defying nature and assuming nature had been conquered. This is hubris, on the part of American administration officials, members of Congress, engineers, management officials, and contractors, etc., across decades, culminating in the Challenger disaster.

The 'Challenger Tragedy' is what you could call the story leading from the end of Apollo to the loss of Challenger, and its immediate aftermath, such as the hearings, etc.

Likewise, the 'Columbia Tragedy' would have a similar narrative background, with its own tragic flaw: management deciding to eschew on-orbit imaging because there was "nothing we can do," if damage was found, anyhow."

Both are sad, dramatic events, but not tragedy. I take a contrary view to what yet another commenter wrote, that it was offensive for you to compare real loss of life to fictional loss of life. To be more accurate, people calling the loss of either shuttle a tragedy are themselves using literary terminology to oversimplify a complex series of decisions and actions into a cable news soundbite, and this oversimplification ("The astronauts' deaths were tragic") cheapens, in my view, the loss of seven Americans engaged in the noble pursuit of knowledge and understanding.

And with that, I shall adorn myself with aerogel pants and await the flaming...

Am I callous?

[Anonymous Coward]

I was in preschool or something when the disaster happened. I had no awareness of it until many years later.

But when I think of the disaster now, I have the somewhat odd reaction that I don't really feel that the real tragedy was the loss of Challenger and its crew.

When I think about the 20th anniversiary of Challenger, the tragedy I feel is that it seems like NASA has done almost nothing of note since then.

It seems like somewhere around the Challenger disaster, the pioneering attitude of NASA that had been its hallmark up until then took something of a backseat. Somewhere around 20 years ago, probably not at Challenger or because of it but certainly sometime around then, NASA changed from being a truly important thing of importance to the public to just being something the government does. 20 years later, the manned space program has not progressed one single step beyond where it was when Challenger blew up; we're still stuck using the exact same shuttle fleet, and the manned program has been entirely preoccupied with the maintenence of a couple of space stations that aren't really that far beyond SkyLab and whose crews are preoccupied just keeping the things in the sky. NASA has had a small handful of true triumphs with its unmanned probes since that time, but the successes have been far between and have tended to receive only a fraction of the attention given in the public eye to NASA's failures.

And when I think about this, and realize that it represents, essentially, the loss of the nation's manned space program sometime about 20 years ago, it tends to overshadow entirely in my mind the tragedy of the loss of Challenger's intrepid crew sometime about 20 years ago.

Is this a callous response, or a reasonable one?

What about the other one?

[EBFoxbat]

Am I the only one that thinks that Columbia was the worse of the 2 shuttle crashes? I mean really, Challenger was catostrophic but was unsurvivable once the SRB ignited. Columbia was in orbit for weeks with its fatal problem in view of the entire planet had anbody thought to look. They say nothing could have been done had they found the damaged in orbit, but I have this funny feeling that we, as a planet, probabaly would have come up with something and not let them run out of O2.

Re:This is one of the problems.....

[darklordyoda]

So when NASA tries to keep costs down, people say they're cutting too many corners and endangering lives, and when they spend extra for the quality, people say they're too bloated and need to run things more like a business.

People will complain no matter how NASA runs things, I say give them a bigger budget than the measly amount they get now and see what they can do with it.

And yes, 16 billion is measly when you consider that it seems sometimes like they're our NIH for everything not health-related; that is, they have a finger in every stewing "pot" of research.

OK, one correction is needed here...

[JetScootr]

It was a tragedy, an accident, a misfortune.
A tsunami that kills 125000 people and makes millions homeless is a disaster. A hurricane and weak levees that kill hundreds, combined with a helpless Department of Homeland Security that unhomes 1.3 million, that's a disaster.
An earthquakeor volcanic explosion that kills hundreds or thousands and destroys entire towns, that's a disaster.
A vehicle accident that kills 7 people is not a disaster, no matter how expensive the vehicle is or how famous the people are.
It is the "Challenger Accident", not the "Challenger Disaster".
Keep some perspective.

  (9) "Hov'ring there" will constitute a highly reliable signal that a flight emergency is imminent.
  (10) Forecasts of shouting winds are available from the local FSS. Encounters with unexpected shouting winds should be reported by pilots.
  (11) Pilots flinging eager craft through footless halls of air are reminded that they alone are responsible for maintaining separation from other eager craft.
  (12) Should any crewmember or passenger experience delirium while in the burning blue, submit an irregularity report upon flight termination.
  (13) Windswept heights will be topped by a minimum of 1,000 feet to maintain VFR minimum separations.
  (14) Aircraft engine ingestion of, or impact with, larks or eagles should be reported to the FAA and the appropriate aircraft maintenance facility.
  (15) Aircraft operating in the high untrespassed sanctity of space must remain in IFR flight regardless of meteorological conditions and visibility.
  (16) Pilots and passengers are reminded that opening doors or windows in order to touch the face of God may result in loss of cabin pressure.
