Rest in peace to those who died in the Challenger disaster.

This video inaccurately depicts what caused the breakup. The side mounted boosters were solid fuel rockets. The fuel inside them had the consistency of an eraser. This is not fuel that can leak. There was no fuel leak from three solid rocket booster. Rather the failure of the O rings allowed rocket exhaust to leak out the side like a blow torch and damage the mounting strut that attached the booster at the bottom allowing it to swing and thus tear the shuttle stack apart. Furthermore, the O rings were not "faulty," they were simply not designed to properly seal outside their designed temperature range. It was too cold. Morton Thiocol engineers knew that and they pleaded with NASA not to launch. NASA coerced Morton Thiocol management to sign off in the launch.

This is inaccurate, nobody signed off on the launch. The booster didn’t tear anything apart, aerodynamic pressure did. The fuel leaked while ignited. The tolerances of the joints were outside of the design. The booster leak punctured the tank causing the cryo fuel to loose pressure and the tank collapsed. You don’t know.

It wasn’t just children watching it live on television, MANY children took a field trip to the beach to watch the launch. I had a boyfriend years ago who lived in Titusville and watched it from the beach. I’ve always wondered what kind of effect that would have on people.

Not a fuel leak; SRB exhaust gases leaked through the compromised o-rings and burned a hole in the external tank.

@takashitamagawa5881

SRB exhaust gases indeed but the picture is complicated. The story I heard was that initially the exhaust gas residue, one component of which was aluminum oxide, formed a glassy seal over the leak which for a while contained the booster combustion pressure. Wind shear as the vehicle continued rising broke that seal, which had no flexibility, and caused the plume to blow out of the booster casing and impinge on the external tank and the strut holding the booster.

@f62darkstar

no....the plume from the failed SRB joint burned through the lower strut supporting the lower part of the booster....when the strut failed, the booster upper section punctured the tank causing the fuel to leak and create the big fire ball.

While attending Mission San Jose Elementary school in Fremont, California, I can confirm that my school watched the launch on television via CNN and we saw it happen live after the explosion. The teacher immediately turned off the TV. We were ushered outside and we were sent home for the day.

The only crewed launch vehicle with zero abort or escape possibility.a thousand potential failure points that can only lead to complete catastrophe. It should never have been considered an operational, production craft, but a highly risky experiment. It held us back from getting anything happening in space, and is still holding us back with the SLS boondoggle.

My school was one who was showing a live broadcast, but I wasn’t watching it at the time it aired and heard about it right after it happened. Incredibly sad and we were all so excited for Christa to be part of the space mission. Rest in peace

We all watched it live on tv at my school. Many watched it live on tv. I dont know your source for this video but im saying that they are wrong, and im sure your comment section will prove me correct

We were all watching"live" in the choir room. To say we were devastated would be a gross understatement. RIP

I was in the 4th grade and we watched it live. As a boy I didn’t fully realize what had happened until my teacher explained it. A real shame that those kids had to watch their teacher pass like this. Additionally, it’s a real shame that NASA, One of the worlds most respected scientific organizations in the world would push aside and ignore such glaring warning just to push the launch through, sacrificing those brave people on the Challenger. It sadly shows what the government thinks of its people. R.I.P. to all of them.

That wasn’t a photo of Mike Smith, and the pole and parachutes were adopted AFTER the Challenger accident.

I was on 3rd grade watching in class and when the explosion happened my teacher walked over and turned the TV off and said nobody speaks yet we're going to pray for the souls of those folks and for their families then we can see what's happened. We did and she turned the TV back on and said anyone who wants to can go sit in the hall and read if their uncomfortable and not one of us moved. She did her best to try to explain what was going on as best she could and after awhile she said this has been a heavy day kids maybe we should go outside and write our thoughts out for a bit and then we can share them. We were kids we knew that we just watched people die most of us it was something we'd never experienced we had watched a bunch of live interviews that christa had done so it was like we kinda knew her and so it was a strange feeling. But Mrs Dumas handled it awesomely. One day I'll remember till I forget it

I was one of the children that saw it live. Same with the twin towers (but that was on the news before I went to school when I saw it). Ya know, it just wasn’t easy being schooled back then.

I was in VT grade school, We all were loaded into the cafeteria and watched it on a VCR TV from the library, They quickly huddled us back to the classroom to get back to school work to make us forget about what we saw. Contrary to what this narrator is saying, I was told many times this was one of the most watched shuttle launches because of the civilian teacher on board.

Watched live in school.

Funny, I just saw Dr Kirwin last week at a conference.

I remember that day very well was in my senior year of high school we had a snow day off that day watching breaking news

At the time I was a USAF active duty Range Control Officer (RCO). I remember it well. It was a very sad day. Think of the SRB segments like coke cans place one on top of the other only with a tang and Clovis. Take your right hand and make a V shape between your fingers and thumb. that’s the clevis. Place your thumb against the fingers on your left hand. That would be the tang that mates with the clevis. The stack is not rigid and it does flex during the launch sequence. When the SSMEs ignite the entire stack “kicks back” about 12 inches as I recall. When the stack swings comes back to about 12 O’clock, the SRBs ignite and off it goes. The SRB segments flex some during all this.

So, what you're saying about the O-rings is that they weren't defective, they were just being used in conditions that they weren't designed for. Also, it was an exhaust leak, not a fuel leak.

Most of the northeast US had a snow day that day. I feel like the numbers that watched it live are legit. The same cold fron that affected Florida dropped snow on the eastern seaboard

I was at home sick for some reason and watched it live. I just remember crying pretty much all day. So incredibly sad.

i was 13 at the time this happened. i was home from school that day. Where i lived all i had to is just walk outside my front door & watch it go up. for some unknown reason my brother was acting like an a-hole that day & refuse to let me go outside & watch it go up. later my mom called us & told what had happen. i was very pissed at my brother that day

Anyone have any idea how dangerous being an astronaut is? Just one little problem can lead to a disaster.

@Infinite-void908

Well there have been three separate incidents where astronauts have died: the 1967 Apollo 1 fire which killed three astronauts, the space shuttle Challenger disaster in 1986 which killed seven astronauts, and the space shuttle Columbia incident in 2003 which killed seven astronauts. There's also the notable Apollo 13 incident where the crew almost didn't make it back. If one thing goes wrong with these spacecraft, whether it's a big or small issue, that could potentially lead to several things going wrong which could result in a catastrophic failure. Although being an astronaut today is safer to an extent, there's still a lot of risk involved. The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.

Yet they wouldn’t have it any other way.

There were several different temperature criteria for the SRBs. Any analysis of a disaster tends to allow hindsight bias to creep in.

I’m not aware of any mythos surrounding the Challenger disaster.

I was in kindergarten, the teachers had rolled one of those old tv’s into the room. I remember the horrified looks on all the teacher’s faces. And a bunch of young children that really had no idea what they were seeing. Crazy

One little known fact is that the Challenger shuttle carried scientific equipment to observe Halley's Comet that year and since they didn't launch the next shuttle until years later, they missed that opportunity to get that data. Even though the comet was not as close as it has been for past trips around the sun, they would have had some great data from it had they not had the disaster. Now the next time Halley comes around will be in 2061 for those that are still around and this time it will be much closer to Earth than it was in 1986.

I watched it live in my class 3rd grade we went wow nice fireworks

Watched it live in class… watched it fall too long.

It was not fuel, but hot gasses that leaked from the starboard SRB.

That one guys brother had an awesome name

I have seen the data for all previous shuttle launches regarding the solid booster o-rings. Proper analysis clearly indicates the low temperatures were a major issue. The decision process used a subset of the data that gave an incorrect conclusion. Very sad.

This was mostly the best video I have seen on this event. I was actually living on Merritt Island and I was sick and home from school. I went out to feed my rabbits oblivious of the launch and heard a neighbor Gasp in an adjacent yard. I turned to look and seen her looking behind me. I turned to see the Big round cloud with 2 rockets flying off. I thought to myself what a weird way to launch a rocket and I went in the house. When I got in the house My Mom, Dad and Brother were all looking at the tv screen with their mouths open. I got so I could get in view of our Hitachi TV in time for a replay. Then I knew what was happening. I noticed the nose of the shuttle coming off and quickly pointed it out. But being this close to the Space center I have had people close to the situation (mind you this was around 30 years ago and I have no way of connecting with them again as I have moved numbers changed and honestly only remember one name and he has passed) That they were friends of the dive team tasked with bringing the nose cone up. That the astronauts were out of their seats and they had not been ripped apart, The other disturbing thing was they were ordered to cut the nose cone up. But I do not remember hearing any explosion.. I remember a Delta that exploded over the launch site years later, I went out to see the launch and upon opening the door it got blown back by the shockwave of its explosion . So thinking back to that day .. I do not remember even a rocket rumble. But thank you for not ever saying the shuttle blew up you actually told it like it was.

I was in high school symphonic band, and the announcement came over the PA system. Almost immediately our director insisted that we pick up our instruments and start playing again. There’s a reason we called him Mr. Potatohead. grrrr.

Here's a fact ill never forget The Chicago bears was supposed to visit the white house that day after winning Superbowl 20

Wow, no mention of Roger Boisjoly, who had he been able to prevent Challenger's launch, would have gone down as a national hero. Shame on you for omitting his name.

Shame this kind of stuff is very dangerous risky business. But that's the fact of it at the end of the day. RIP

The shuttle design required it to be able to fly out of SLC-6 at Vandenberg Air Force Base, where the ambient temperatures are frequently below that at KSC on that day. During the final review before launch, NASA management SPECIFICALLY asked the booster manufacturer if their product met the requirements. They insisted it did. And this was BEFORE cell phones so the Thiokol engineers had no way to communicate with their management in the meeting.

Practically everything you said is wrong. The cold temperatures in Florida were record breaking lows that were not normal, and it is even less likely for the temperatures to get that low along the California coast. Morton-Thiokol discovered the problem with the o-rings over a year before the accident. They immediately brought their concerns to NASA. NASA engineers had several large presentations where the problems were openly shared with several different NASA divisions including upper management. NASA even degraded the O-Rings from a fail-safe component to a Critical-1 component meaning that a failure could lead to a catastrophic fatal accident, but NASA kept accepting the additional risks. The night before the launch there was a conference call between NASA management, Morton-Thiokol management, and engineers from both in which basically everyone except the upper management refused to sign-off on the launch. NASA management refused to accept the evidence as conclusive and basically bullied Morton-Thiokol management to sign off on the launch despite them specifically trying to stop the launch.

You forgot the myth that NASA is professional, competent and knows what it's doing. It is a myth that the o-rings were faulty. They did their job under the stipulated conditions.

I watched it live at home I was 10 years old when it blew up I said what a piece of crap and changed the channel to watch looney tunes cartoons

How could you get so much, so wrong? Fuel leak from the SRBs? Ni, there never was thought of shutting them off mid-use. It wasn't and isn't possible. There is no abort possible while those boosters were firing. Where did you get that nonsense?

The rings were not, "faulty". Just one of the many stupid errors in this video.

Rest in peace

It was rocket blast not fuel that leaked.

What myths???

Very sloppy writing. There's no "liquid fueled rocket" in the STS stack. There's a fuel tank, and that feeds the main engines on the orbiter. And the accident wasn't caused by a fuel leak. It was caused by exhaust gasses from the solid rocket boosters burning through an o-ring, and then destroying the lower mounting point for the SRB. When that came loose, the SRB crashed into the external fuel tank, and that's what made the "fireball".

The 'o' rings were NOT faulty. They were used improperly. NASA knew there was a issue during accent snd could have aborted but didnt

I remember whatching it on tv in newzealand , diffently a oh shit moment for every one across the globe interested and or invested the space race ( for want of a better word)

Only after the accident happened that Reagan delayed it by one week. How much did the president and the state of union affected NASA’s decision to launch that morning? I don’t know but it was definitely in NASA manager’s mind when they decided to overrides the engineer and launch that morning.
