TOP 15 ENGINEERING FAILS - what were they thinking?

Engineering is an exact science. One false calculation, and it’s all over. Engines can fail, buildings can collapse, and bridges fall into the sea. These instances serve as reminders that even the most advanced and carefully planned projects can encounter unforeseen challenges, resulting in remarkable blunders and valuable lessons. Join us for today's video as we count down the top 15 biggest engineering fails and mistakes.

I still get irritated when I read someone talking about the twin towers (The World Trade Center) like they were a failure and placing some blame on them for collapsing and stuff like this let's people see what actual failures of buildings are. Far from being a failure in the engineering and building the towers actually held up remarkably well. A fully loaded 757 with full gas tanks of jet fuel hits pretty much any structure and it is coming down. The fact that they held together as long as they did and long enough for many to evacuate to safety is a beautiful thing. Especially the 2nd impact which took out basically 2 opposing corners of the building midway up. Talking about this brings back a lot and reminds us how stupid and short sided many people can be as they quickly forgot why we originally went to war over there.

Skylab did fall on Western Australia, but to say it fell on populated areas is a little dramatic. WA is the size of Western Europe, with the population of a single medium-sized city mostly concentrated in and around Perth.

The local council, where the pieces landed, decided to bring NASA'S stress levels, if they were elevated at all, back down to earth by sending them an official fine for littering.

As a civil engineer, I MUST point out that every failure is not because of engineering. Contractors trying to earn more money will often build with cheaper materials, or do things like only putting in 4 bolts at a joint where 8 bolts were specified by the engineer. Manufacturers of materials will also produce substandard materials to ‘earn’ more money.
As the saying goes, engineers don’t make any more money specifying lower than adequate designs, but contractors and material manufacturers DO make more money shaving corners.
Another saying says “follow the money”. There is incentive ($) to actually build a structure poorly. The engineer gets paid the same no matter how it gets built.

Usually, "engineering fails" aren't the engineer, but the "businessmen" in charge. Businessman builds something for profit, engineer builds for quality, businessman cuts corners, and the engineer gets saddled with the blame. Be careful who you work for. I've spent a fair bit of time getting away from people with bad business practices. So has my father who got the rare satisfaction of telling Ford to stuff their pride where the sun don't shine because their processes were screwing up one of his company's products.

It's crazy to think that there's still structures that were built 500 y.a.-1000 y.a. and some beyond that are still standing and yet with all the computers and materials used today even the most modern engineering fails. I mean roman concrete used in ancient viaducts is still holding up and used 1000 or more years after being built..

You are showing John Hancock in Chicago, not the one in Boston that was once called the cardboard tower from boarding up windows when glass cracked or fell.

Excited, surprised, scared – this video took me through a whirlwind of emotions. Catastrophic failures are no joke!

[roelheijmans]

10:55 number 8, it starts with the John Hancock building in Chicago, but all of a sudden we are in Boston. Two things got messed up there 😉

[RavenFilms]

11:46
In Boston huh?
It even says in your footage that it’s Chicago.

Engineering failures? Several of these had nothing to do with the engineering but rather management decision failures. Ford Pinto for example.

[reallyseriously]

Tacoma Narrows colapse. I've seen the fotage a hudred times and it never gets old. Just stunning.

[canisqmajoris]

The video is showing the John Hancock Center in Chicago, which is 100 stories tall and not the building in question. Eventually it does depict the correct building, the John Hancock Tower in Boston.

[normfarris]

I remember the Hancock tower mess. At one point, it was called the Plywood Palace, because of the plywood patches all over the outside of the building.

[mclovin]

When glass falls off a building, this is called glass falling. You learn something every day...

[ydenneki]

5:14 The scene from 1984's "Top Secret" with Val Kilmer, one of the best spoof films ever made (along with the Airplane and Hot Shots duologies).

[hjkaye]

Definetly a mixup on the Hancock tower segment. First photos were not the Boston building.

[garymiller]

Absolutely terrible disasters. There was one dog that lost its life in the Tacoma bridge collapse. Let's not forget it. 😢😢😢

[netgnostic]

The Bhopal situation was more nuanced than that. Union Carbide was prevented by (corrupt?) local officials from having actual authority over it. They couldn't force the local owners to spend the funds necessary for badly needed maintenance and repairs - which was the eventual cause of the disaster.

[canisqmajoris]

Artz Pedregal was NOT a welcome addition to the neighborhood, and it's worth mentioning that the rooftop garden is suspected to be the issue. The part that failed was a cantilevered section; the hillside had nothing to do with it.

[alunchurcher]

One big problem has been overlooked with this video and thats, they get the money to build something but then think it will not require long term maintainance and this maintainance is either patched up or left and covered up. You can build miles and miles of roads but they will require regular maintenance which increaes in cost constantly.
