This is why I always tell people in the manufacturing industry that the littlest details cause the biggest problems.
Almost all disasters are caused by a number of small details, that each on their own would be harmless, to combine.
It's extremely easy to make careless decisions when consequences are paid by others.
This is what happens when you don’t listen to the engineering experts that you hire especially if they had warned you about multiple fatal flaws since the start of the shuttle program the O Rings in the Solid Rocket Boosters being one of them and the foam impacts too and because NASA decided not listen and take action we lost 14 brave astronauts in the shuttle program
That's true but there are hazards associated with space flight. Unfortunately they were accelerated in this circumstance. It was probably an ill fated decision. I agree
Exactly
From what I understand the foam impacts were unexpected damage that broke heat shield tiles. They didn't think it would damage the😢 shuttle
@@stanleydavidson6543 it’s always been that way the thing you suspect the least always ends up being the most deadly
@@stanleydavidson6543 WRONG SHUTTLE. This is about Challenger, not Columbia.
HBO gotta make a mini series about this like they did for Chernobyl
I was in North Miami atop the Golden Glades interchange when the rocket took off. It was a super clear day. I watched the explosion as it happened. It was far so I didn’t realize what I was looking at until I got back in my car. The radio announced the explosion within minutes. Even after all these years, knowing I watched those amazing people die, live, makes me sad.
I thought you were full of 💩 at first but then I realized I misread, and Miami although far is within range
I was in West Palm Beach, on top of a Best Buy pharmacy replacing a a/c filter and saw it all happen. I got down and went into the pharmacy( I knew the two pharmacists had a small TV. That is where I learned that all seven had perished. Then later on reading it was because of an O ring that failed because the higher ups Wanted it to be launched THAT day! I sure hope these higher ups have learne a very strategic lesson from this. Of course, it doesn't matter now that they have stopped using the Space Shuttle
I stayed home from school on this day to watch the launch. My uncle, aunt, and myself were all about the space program and so excited to see its progress. We were immediately heartbroken and in tears of disbelief. We all said at the exact same time…”NO…NO…NO! This can’t be! I will never forget this moment till the day I die. All for money. That’s why this happened. If they would just have waited a few more hours till the temperature rose🤦♂️
The Head Engineer (Allan McDonald) that spoke to the Investigation Committee is one of the most HONORABLE MEN I have EVER SEEN! GOD BLESS YOU SIR!
i was only 9 but i kind of remember watching this in the gymnasium.
RIP
@11:40, there were no launch suits in 1986. The crews launched wearing the blue coveralls they'd wear during the flight. It was the "just an airliner" mentality that NASA had prior to the disaster. (The first crews, during the earlier test flights, when it was just the commander and pilot flying, did wear traditional pressure suits. But, by 1986 those had been deemed needless.)
One thing this video missed was the best and most critical example of schedule slippage and pressure: the 24th flight, STS-61-C Columbia. Columbia had been scheduled for December 18, 1985, but was delayed six times until January 12, 1986. This in turn delayed STS-51-L Challenger's mission since components from Columbia were needed for Challenger's. The mission's duration was curtailed from seven down to four days to get Columbia back, but due to unacceptable landing weather, Columbia could not land at KSC, but at the alternate site at Edwards Air Force Base in California, which necessitated several days in getting the orbiter back on the 747.
Had Columbia not been delayed so severely, it's likely Challenger would never have seen that severe cold weather on January 28, and would most likely have launched safely into orbit.
Had they launched that Sunday, they would've been good too. The weather prediction was wrong, imagine that. They could've launched Monday, but they had problems with a locking bolt on the crew cabin door.
@@Kyle-gb9dq True, but they never would've been close to being pushed up against that schedule "wall" had Columbia launched in December or even very early January.
The Columbia launch preceding the Challenger disaster should not have taken place at all and the main payload on board could easily have been put back to a later mission. The unnecessary Columbia flight added needless pressure on management to launch Challenger, even in conditions too dangerous to launch. Challenger could and should have been launched earlier when the weather was warmer and likely would have reached orbit safely. Of course, though, the o-ring problem would not have been addressed if there had been no no tragedy, the tragedy would probably have happened On a later flight instead.
@@olivergrumitt2601 Dead wrong! Many factors in which played a role in the demise of the Challenger. The key was the below freezing temperatures. Did not give the o-rings time to bounce back to do their job. The mere fact that the strut mount where the plume blew out which "torch" the mount off caused the SBR (right) to put stress on the external tank (the upper) as the SBR broke away from the aft causing the E. T. to breach which gave the illusion the launch blew up (exploded). But in actuality this was just the E. T. depressurizing because evidence clearly shows there weren't any "shockwaves" from a typical explosion. The conclusion is the Challenger disintegrated from the plume causing the strut mount to dislodge from the SRB (right) which caused the E. T. to rip apart causing the rest of the components to break apart as well.
You know what happens to rubber seals when they are frozen and subjected to those kinds of forces eh? There was ice on the chain link fence in West Palm Beach that day, I watched it come apart from there. I had seriously bad feelings about their decision to go up on such a frigid day.
Kinda says something when you pick the southernmost point in the (contiguous) United States (would've been cost prohibitive to use Hawaii) and it STILL can get icy cold in the "Sunshine State.."
The voice over for the Italian astronaut is excellent
That thumbnail does a real disservice to this tragic event.
Bless those who crewed Columbia and Challenger. Bless their hearts of the supervisors who refused to listen to the experts
When you get Richard Feinman telling you you fucked up, you’ve done fucked up.
47:30 - “…hastened the demise of America’s Space Shuttle.”
The Columbia disaster hastened the demise of the shuttle, not Challenger.
Before Columbia, NASA was making plans about how to keep the shuttle flying well into the 2030s.
Their biggest concern when Shuttle program began was something from the tank foam hitting the shuttle during launch. Guess they didn’t think O rings weakening was a top concern. Ironically their top concern would happen with Columbia years later.
Pray Peace to the Immortal Souls of the Space Mission.
Every regulation and policy change is written in blood.
I’m surprised that as the O-rings were a part that, even with redundancy, was a single-point failure, they weren’t preheated to performance parameters by wires or such prior to lift off.
I mean, car windshields can be defrosted, why couldn’t this crucial component be?
19:55 How the heck do you get hired as an astronaut for the Space Shuttle and not speak English? Did he have a translator go up with him? Doubt all the other astronauts spoke Italian.
Is that photo in the thumbnail real? If so, was it really from the same launch?
Another example of, “Always listen to your engineer!”
Worst thumbnail on the Internet
And the lady with the final green light still works for nasa....smh.
Great explanation in the simplest terms. Thank you.
The ones that made them launch should have been locked up 4 life and nasa should have had 2 pay out the ass
This, along with the Smarter Every Day's presentation towards the folks now managing the Nasa missions back to the moon is really fascinating in creating a culture of communication and openness. Very interesting.
Oh💍 🏴☠️ Bless the brave Challengerr crews hearts!! 💐
If you want to be a real know-it-all at parties you can tell your friends that Challenger didn't really explode. It disintegrated in a cloud of burning fuel all being released at once. There was technically no detonation, so no explosion. We just call it an explosion as a kind of shorthand, and because it looked like one. Be prepared for some blank stares, though.
Broke apart!⚡️
Remember, this tragedy happened because of Money.
They were warned.. 😔
It appears that unless the engineers could not 100% guarantee there was going to be a failure, NASA decision makers were going to launch. Wonder is their decision would have been the same if they had a family member on board.
Challenger didn't exploded. It break up due to aerodynamic stress.
It's kind of common sense cold and heat comming together makes cracks and gaps
Totally preventable
Good morning to you from Kenneth D in Hamilton New Zealand 😂😂😂😂😂😂
I was at the corner of the grass when this happened and thought gee golly what’s going on
The O rings were FROZEN. THEY KNEW. THEY SHOULD HAVE NEVER EVER BEEN IN THAT SHUTTLE THAT DAY. IT WAS A GREEDY STUPID HUMAN ERROR. THESE HEROES WERE MURD3R3D.
That door that was faulty before liftoff should have been a sign right there. NO GO FOR LAUNCH. REST PEACEFULLY TO THE CREW.
31:40 Wow, just wow
This thumbnail was made with midjourney and doesn’t make sense haha
Anything A.I. is dumb and needs to stop. It's lazy.
I never knew Reagan gave that speech
they gave it away in the first minute of the video. lol
Did not explode, broke apart, and yes they fell for 3 minutes to there last moment
bedtime for ronzo
The thumbnail looked like the challenger got caught up in a atomic bomb
Follow the money. I wonder if the airforce was realy aboard. If they used the shuttle would it cut there budget? I really don't know
Dudes got some serious British teeth going on
managment shouldve listened to engieers
Were the astronauts aware that the Morton Thiokol designers refused to authorize the launch?
NO
The STS was ungodly unsafe. Surprising they didnt all explode
The saliva noises his mouth makes is disgusting.
Challenger didn't explode, it broke up due to aerodynamic forces. Fix your title.
It didnt explode. It was forced from the delicate slip stream and the Shuttle airframe disintegrated. There was no shockwave of an explosion. Read the book "Challenger".
A part of me suspects these failures are intentional, in what are psychopathic attempts to captivate people emotionally, to garner continued support for the programs.
Entirely plausible, considering the very bad conditions for launching that day.
Nobody was aboard. Never was, never will be.
What a beautiful Psyop.
There are also people who deny the things that happened even if it hits them in the face and it is even proven by hard facts ,evidence and data all you can do is ignore these people because they’re opinions will never change
Take your meds.
@@giminai8000 - well said brother!
The hard facts being they are still alive and well now living protected lives for participating in these types of CIA Psyop programs called FEMA crisis actors.
The other commenter most likely believes that 911 was carried out by duder in a cave & the recent Hawaii fire was a powerline spark on a windy day.
Ok. I'll go with what some head up ass youtube comment guy says instead of piles of indisputable evidence and actual smart people called engineers.
What a fucking moron.
Please go troll somewhere else with that stupidity!
The Challenger NEVER exploded. Get you facts straight.
Good God that there was no people inside....
Jerk
Because the space you all speak of does not exist 🤦🏾♂️ 😆
What are you talking about?
@@teclabs57oh, the usual conspiracy goodiness. Best to just ignore it.
@@justinthomas7222 nice to know you don’t think 👍 lol
@@teclabs57 you wanted to go to didn’t you? Lol fools
@ajclark1530 no I'm staying on our lovely planet.
Thank goodness for SpaceX. NASA sucked. Cost plus contracts suck.
NASA saved SpaceX from almost certain bankruptcy with the CRS-1 contract. Just ask Elon Musk.
Dumbest comment ever.
They should've sent those bureaucratic maggots on the next shuttle flight, I'll bet they'd change their tune pretty fast. I assume, according to them, that people are expendable, as long as they can launch on time. What a f**ked up program, there's always gonna be risks but that was total bullshit, lot of people died because someone was worried about losing their job. 😢
