Summary of Los diez grandes desastres tecnológicos

00:00:00 - 00:45:00

The video discusses ten technological disasters that have caused deaths and injuries. These include the crash of the Pan Am Flight 103 over Lockerbie, Scotland, in 1988, the TWA Flight 800 explosion off the coast of Long Island, New York, in 1996, the Air France Flight 447 crash in the Atlantic Ocean in 2009, and the recent crash of the Tesla Model S in California. Each disaster is analyzed in detail, and it is shown that each was caused by human error. The final section of the video discusses how these disasters have been widely reported in the press and have affected the public's perception of technology.

• 00:00:00 The video discusses 10 technological disasters which have had a significant impact on human history. Some of these disasters, such as the Hindenburg disaster, have become infamous and are known to many people. However, there are also many disasters which are less well known, such as the Helium crisis. In total, 36 people died in the Hindenburg disaster, and it is still not clear how the hydrogen gas explosion happened. Nevertheless, the disaster led to the development of new technologies, such as air travel, which had a huge impact on human history.
• 00:05:00 The video discusses ten technological disasters, including the first airplane passenger crossing the Atlantic Ocean, commercial aviation becoming the new hope for the future, but much earlier than humans would soar through the skies, the sea was the human frontier to conquer. Technology is the tool used by the human race to mold certain forces in their own favor, but often what is easy to harness can be dangerous when it goes wrong. On September 29, 1944, the ferry Estonia began its voyage across the Baltic Sea from Estonia to Sweden. Shortly after boarding, the crew realized that the ship's heavy watermark would prevent them from closing the gate to the cargo hold and began to panic as the cars and passengers flooded into the boat. The emergency release valves on the ship's bow opened and water quickly filled the cargo hold, submerging the cars. The ship quickly went down, taking with it 800 passengers and 52 crew members. 197 passengers survived, and the sinking of the Estonia became world-news. The disaster was due to a combination of factors, including poor construction, the use of less cement because of the high cost, and lax safety standards. Twelve officials were arrested and charged with corruption. The president of the stores was sentenced to seven and a half years in prison. The public still
• 00:10:00 The video discusses the ten biggest technological disasters. These disasters range from a bridge collapse in 1940 to an air crash in 1977, and all have had devastating consequences for those involved. One of the most famous disasters occurred with the Hindenburg, a German airship that crashed in 1937 after being fatally damaged in a fire. The video also discusses other technological disasters, such as the first air accident, which killed Orville Wright and his passenger. Despite these tragedies, technological progress has also led to some great achievements, such as the development of aircraft. However, even the most advanced technologies have their limits, and human error can lead to disastrous consequences.
• 00:15:00 The video discusses ten technological disasters that have caused deaths and injuries. These include the crash of the Pan Am Flight 103 over Lockerbie, Scotland, in 1988, the TWA Flight 800 explosion off the coast of Long Island, New York, in 1996, the Air France Flight 447 crash in the Atlantic Ocean in 2009, and the recent crash of the Tesla Model S in California. Each disaster is analyzed in detail, and it is shown that each was caused by human error. The final section of the video discusses how these disasters have been widely reported in the press and have affected the public's perception of technology.
• 00:20:00 The video discusses the ten biggest technological disasters. These disasters include a plant that manufactured pesticides that affected the human nervous system, a volatile and toxic chemical that react with water, creating heat and is extremely dangerous, causes of fatal work accidents involving machinery, gas-related accidents in ships, planes, and automobiles, asphyxiation from gas fumes, electric shock, falls from vehicles, poisoning from plants, animal venom, insect bites, and supplements containing pesticides and herbicides. The official death toll from these accidents is estimated to be 3000, with 100,000 injured. The plant that manufactured the pesticide that caused the 1984 Bhopal disaster was eventually dismantled and sold as scrap metal. What would have happened if the plant had been in Massachusetts or Texas? This is a topic that needs to be addressed in a more thorough way in the 21st century. Many students followed the launch of the Challenger space shuttle with excitement, only to see the explosion that killed seven crew members. Investigations suggest that the crew survived the explosion but died from the impact of the free fall 16 kilometers into the Atlantic Ocean. The failure of the Challenger space shuttle was a major event in the history of America, and it left a lasting impression on many college students who saw the explosion. A dream American project
• 00:25:00 The video discusses the consequences of the Challenger disaster, which killed all seven crew and caused extensive environmental damage. The video interviews people who were involved in the disaster, including the engineer who designed the propulsors and the lead engineer on the project. They express their concern that the gas jets could escape and cause a gas explosion. However, the tests showed this to be a problem only in low-temperature launches. The morning of the launch, it was 11 degrees Fahrenheit, but the weather forecast predicted freezing weather the following day. However, the NASA bosses decided to go ahead with the launch anyway. The disaster halted NASA's space program for two years.
• 00:30:00 In 1989, an oil spill from the Exxon Valdez resulted in a massive environmental disaster in Prince William Sound in Alaska. The spill killed more than a thousand marine animals and left the area's ecosystems devastated for many years. While the debate initially centered around the captain's drinking habits, it is now known that the ship's second officer was in charge at the time of the accident, and that he was not adequately monitoring the vessel. For the local residents, the spill has caused a much bigger battle, as 25 of the area's 25 species of marine animals have been affected. Only after several years have the environmental effects of the spill started to recede. It has been eight years since the Exxon Valdez disaster. In order to ensure that our beaches remain clean and safe, we need to find other sources of energy. We hope that by doing so, the marine wildlife can return to living in the area and sustain ourselves. In the early 1980s, many residents of Kiev and nearby Russian cities saw nuclear energy as a necessary and cleaner alternative to oil. However, it was also the cause of a technological disaster, the Chernobyl disaster, in 1986. At the time, many people believed that the nuclear energy was a safer and cleaner option
• 00:35:00 After the Chernobyl nuclear disaster, Swedish scientists discovered elevated radiation levels in the environment weeks later. The Soviet government finally made an announcement about the disaster, showing a small video clip of an uncontrolled fire in a nuclear power plant. The firefighters who responded to the fire were fatally irradiated. The disaster has decreased people's hope in nuclear energy. Although only 40 nuclear power plants are still operational, radiation exposure from these plants is still a health risk for 240,000 years. Countries with operational nuclear power plants include Spain, the core of the Soviet Union, Sweden, Canada, Germany, the United Kingdom, Japan, Russia, and France. The Challenger disaster killed seven people and made everyone sad. However, the Chinese nuclear disaster that killed hundreds of thousands of people passed unnoticed in the West. The breaking of the Chinese dams in the 1970s caused part of Nixon's visit to China to be cancelled. China's population is a quarter of the world's population. Even within China, few people knew about the 7 August 1975 nuclear disaster that caused widespread casualties. The engineering feats of building the largest dam, building the tallest building, or producing the most rice were all seen as national accomplishments in countries with nuclear power plants. China's largest dam required construction
• 00:40:00 In the video, "Los diez grandes desastres tecnológicos," several disasters are discussed, including the Titanic. It is explained that although seemingly static, waterworks need regular maintenance in order to work efficiently and safely. The collapse of a Chinese waterworks in 1963, killing 3000 people, serves as an example of the dangers of poor construction. Even in the face of natural disasters, human error is often compounded, as was the case with the 1975 floods in China. The two waterworks that collapsed due to high water pressure were the result of design flaws and inadequate maintenance. As a result, dozens of people died and tens of thousands were left homeless. Even after the water withdrew, leaving behind 100,000 bodies, diseases such as cholera and dysentery spread. The aftermath of the disaster left 230,000 dead. The Chinese media at the time did not report on the tragedy, making it difficult for rescue crews to arrive. After the events in Yunnan, the world learned valuable lessons about disaster preparedness.
• 00:45:00 Over the last 100 years, technology has helped progress humanity as well as causing some of the largest disasters in history. While the evolution of technology depends on our mistakes being learned from, disasters have an important role in the development of technologies, especially in the case of 20th century technologies like airplanes, automobiles, fiber optics, laser technology, personal computers, and robotics. It is evident that technology has done a lot for us and is currently at the center of civilization. These 10 great technological disasters show that human error is the cause of most disasters, but from these same disasters, we can learn to achieve human progress.
