Une fusée de 68 TONNES et son équipage détruits à cause... d’un peu de mousse.

Idk how the algorithm gave me this weird french/english documentary but I'm here till the end now.

NASA was advised that it might be wise to divert to make a pass by a satellite to get some images of the impact area to see if there was damage and they opted not to do that. NASA was advised to postpone the launch of Challenger because the temperature had dropped to freezing and the o-rings would fail. They opted to pressure MortonThiokol to override their engineers who built the boosters and was pushing to postpone the launch because the cold would prevent the rubber o-rings from sealing the joints between the booster segments. Two Shuttles and two crews vanished for negligence

RIP Rick Husband (1957-2003) William C. McCool (1961-2003) Michael P. Anderson (1959-2003) Kalpana Chawla (1962-2003) David M. Brown (1956-2003) Laurel Clark (1961-2003) and Ilan Ramon (1954-2003)

I was in Dallas the morning the Columbia broke up. I was in the parking lot of Flight Safety International at the DFW Airport. I was late to ground school class as I stood there watching this machine break apart. I will never forget that horrible day.

Suits didn't listen to the engineers. That's why we lost Challenger and Columbia. Gross incompetent negligence from bureaucrats.

Whenever a government agency says"dont worry" then you know its time to worry

I watched the reentry live on a local TV station. When I saw the big piece fall away, my heart just sank, I knew then no one would survive such a break up on reentry. One subject not covered by the video is why the foam was coming unglued and falling off so often during ascent. Ten percent of total launched shuttles had foam come unglued and would strike the orbiter. Also on one of the many videos that was published over the years stated that the originally specified foam formula and glue was replaced with an environmentally friendly type of foam and glue that didn't work as well. I haven't seen that video sense. Very good program. Thanks.

Astronaut Kalpana Chawla’s smile makes me sad every time I see her 😢 RIP

Rest in peace, brave crew, very sad for the families.🌹🌹🌹🌹🌹🌹🌹.

Thank you for using the footage that I shot of Columbia in this documentary.

No one really wants to talk about it, but the more I hear about the last moments of Columbia, the more I'm convinced that the crew knew they were doomed and were definitely conscious and felt physical pain at the end, if only for a couple of seconds.

What on excellent documentary. Very impressed with all the details and the honesty of those people on the ground.

I remember that morning. I’d had to leave my car in a public lot overnight due to mechanical trouble. I narrowly avoided having it towed. Once I finally had it at the garage, I checked it in and crashed in the waiting room. I rested my eyes for a few minutes, then opened them to see the television playing. Columbia’s crew picture covered the entire screen and in that moment, I knew something had happened. I later had to max out my credit card to pay for the repairs, but it didn’t matter. I was still here. Those astronauts were gone. It was a terrible day.

"An accident some years previous..."??? What an odd way to describe the Challenger disaster.

What is shocking is how consistently NASA disregarded safety concerns.

Speed and velocity have so much power. A little piece of foam travelling hundreds of miles and hour can do so much damage. Same as when people think planes can just ditch in the water and be fine, at the speed the plane is travelling, hitting the water is like slamming into concrete. When the plane landed on the Hudson, it was a miracle landing, due to the captain’s skills.

It could be expected that a lump of foam would be so soft that it would not damage anything. But at an impact at several hundred MPH chunks of foam become very energetic and lethal. The prime job of the tiles that covered the wing surface,was to provide fantastic thermal insulation. As the ship reenters , their outer surface gets very hot ( a thousand degrees or more) due to the compression as the air hits the outside and the friction as that air rubs against the surface. Those tiles do a fantastic job of keeping the aluminum structure of the ship reasonably cool during the 20 minutes or so time of the reentry. The tiles thermal conductivity has to be very minimal. To make that low the tiles had to be made of a felt made of thin fibers of a low conducting materiel. A material of that nature would have very low strength and elasticity. With hindsight maybe the wing should have had an additional layer of thermal insulation or a heat resisting steel leading edge. These suggestions would have added weight.

I bought my first semi 3 months before this happened. The night before this my engine threw 2 rods out of the block and I ended up in Columbia, Mo at a hotel. I remember waking up the next morning and turned on the TV to the news and thought "Why are they showing footage of the Challenger?" then seen that it was Columbia. I, like most people, was in shock that it happened again. R.I.P. to the crew and peace for their families.

27:35 so basically, they were worried about spending money than these people lives that are on a perhaps, highly probable damaged rocket.

53:45 On that day in 2003, i was driving to work on FM 1960 in NW Houston. It was a beautiful bluebird day! At approximately 9am, something made me look off to my left... and I saw what appeared to be silver glitter falling from the sky.... a few minutes later, i walked into the workplace, and found everyone looking at a tv.... news flash about the shuttle! It was then that I knew what I had seen! OMG! tragic moments I will never forget!!! 😢
