Two videos show how 80 people from a plane have saved life in the last plane crash. There is triple explanation

After the tragic accident last month Between an American Airlines plane and an United States army helicopter that left 67 dead, on Monday there was a similar scene when it occurred A forced landing of Delta Air Lines’s flight 4819 In Toronto. Two videos showed rawly the scene that the 80 people who went on board and who ended the plane turned. And yet, it did not end in tragedy. How could they be saved? The “miracle.” Delta Air Lines’s flight 4819, operated by Endeavor Air, made a seemingly normal landing at the Pearson International Airport in Toronto until, Suddenly, everything went wrong. As soon as the wheels began to touch the wheel, the plane slipped, hit its right wing, turned on its axis and ended upside down, leaving an absolute chaos scene. But as we said, and despite the violence of the accident, The 80 passengers and crew managed to survivealthough 18 were injured, including an adult and a child in critical condition, although already out of danger. The impact and the fight to escape. They counted at the Washington Post in a report report that the passengers described the impact as “collide with a wall” before the plane turned. When they were face down, many remained suspended by their seat belts, seeing how the fuel slid through the windows and the fire consumed part of the aircraft. Pete Carlson, a paramedic on board, managed to unbutch and drop to the roof of the planenow turned into the ground, before helping others free from their seats. Meanwhile, passengers, in shock, collaborated with each other to get out as quickly as possible. A video recorded by Pete Koukovanother passenger, showed the crew organizing the evacuation with firm and urgent instructions, guiding people through emergency doors in an inverted plane, a rare scenario in aerial accidents. Outside, firefighters sprayed fushes with foam, while black smoke and flames hindered visibility in full snowstorm. How tragedy was avoided. In front of many Other aerial catastrophes More or less recent, experts have been detailing these days how the “miracle” was possible. Actually and as we will see, there is not a single factor, but several that helped that finally there was not a single death. Three were the main factors that we describe. Plane design and safety measures. He Bombardier CRJ900like all modern commercial planes, it is built with standards called “Crashworthiness”which means that its structure, safety belts and seats are designed to maximize survival in case of impact. In this regard, the cabin absorbed much of the strength of the crash without disintegrating, allowing passengers to go alive. According to Graham Braithwaiteexpert in aeronautics at the University of Cranfield, these elements were fundamental for passengers to resist the impact of the overturn without fatal injuries. Professor Michael J. McCormickfrom the Embry-Riddle University, stood out in the post That engineering and aeronautical regulations have advanced so much that accidents that in the past would have been lethal can now result in total survival. Assessment of the crew. Equally important that the design of the aircraft was crew trainingdecisive to organize a rapid and effective evacuation. Despite confusion and chaos, they managed to maintain order and get everyone out of the plane in a matter of minutes, even with the aircraft dump. Here it is important to remember that the regulations of the Federal Aviation Administration (FAA) require that Any plane with more than 44 passengers can be evacuated in less than 90 seconds. However, in this case, the evacuation was more complex because the plane was overturned, hindering the orientation and exit of the passengers. Immediate response of emergency equipment. The third of the key legs. Toronto airport authorities acted rapidlyensuring the area and preventing the fire from extending to fuel deposits. The first air control reports confirmed the severity of the situation: “The plane is face down and in flames”, which led to a rapid mobilization of rescue equipment. According to the norms of the International Civil Aviation Organization (ICAO), rescue teams They must respond in less than two minutes. In this case, firefighters and paramedics arrived at the place in a matter of minutes, stifled the fire and helped evacuate passengers. Causes of the accident. Although the exact cause of the accident has not yet been determined, it is known that landing occurred under wind conditions up to 70 km/hyve accumulated On the track after two recent storms. Thus, the airport firefighters ruled out problems with the track, which suggests that other factors, such as mechanical failure or human error, could have influenced. Be that as it may, in a context where Recent air accidents They have resulted in fatal tragediesthe total survival of flight passengers 4819 is a real testimony of the advance in aeronautical engineering, security protocols and emergency response. Although The images of the airplane burned and overturned They suggest an inevitable disaster, the combination of these factors allowed to avoid the worst. As Carlson underlined In his interview, after leaving the plane I only thought about one thing: “I didn’t care about the cold, I didn’t care how much I had to walk, all we wanted to be out of the plane.” Image | Yyzbrennan In Xataka | The main suspect of the plane crash in South Korea is common in aviation.

The ultrasecure aerial capsule that the US usually uses as an alternative to the “final judgment plane”

He E-4B Nightwatchbetter known as the “final judgment plane”, is a key piece of the National Military Command System. It is a modified version of the Boeing 747-200, such as the presidential planeequipped with meeting rooms and advanced communications systems, essential to execute emergency orders and coordinate the Armed Forces in case the ground command and control centers are inoperative. In addition, this plane is usually used by the Secretary of Defense on its trips abroad, guaranteeing connectivity and command capacity according to the organization of the country’s armed forces. But what happens if no E-4B is available? This is an expected scenario and for which there is an alternative. If the E-4B cannot fly, the C-17 comes into action There are multiple reasons why E-4B may not be operational: routine maintenance, technical failures or even deployments in crisis situations. Even if any of the four copies of the fleet were in a position to fly, it is possible that the authorities decide not to use it for strategic reasons. In those cases, high -importance passengers, called VVIP in English, can move in the C-17 Globemaster III. An E-4B Nightwatch (above), a C-17 GlobeMaster III (below) Here we enter a known field. It is a colossus of four engines originally designed by McDonnell Douglas and whose legacy continues under Boeing. Its robustness is undeniable, but its interior is far from offering an adequate environment for VVIP. The load warehouse lacks connectivity and does not have work stations. To solve this problem there is Silver bulleta kind of capsule that makes the C-17 a transport suitable for high controls. Military personnel install a silver bullet in a C-17 GlobeMaster III When this alternative is activated, The Air Mobility Command and the 89th maintenance group install a silver bullet inside a C-17. The process involves moving the capsule with a trailer, ensuring it in the plane’s cellar and connecting a complex umbilical cable system that guarantee the Safe communication. Jens Stoltenberg in a silver bullet (left), Pete Hegseth inside another (right) Over the years, various images have allowed to take a look inside this ultrasegura capsule. In 2017, the then NATO general secretary, Jens Stoltenberg, He shared a photograph of a meeting inside the silver bullet. More recently, Defense Secretary Pete Hegseth appeared in a video posted in X from inside. The space is reduced but functional: wooden panels, brown leather seats, telephones and safe computers, a bathroom and even a microwave. However, Your time is counted. The Air Force plans to replace these capsules, designed decades ago, by most advanced versions With better connectivity, more current shots, bedrooms and conferences rooms with capacity for up to nine people.

The new space race has created Boomerang scrap. The probability that clash against a plane has also increased

We are launching more rockets to space than ever. Between China and Spacex, they occur releases every few days in a new space race with multiple objectives on the horizon. It’s something that is lowering space transportationbut also generates a new problem: the amount of scrap that orbits our planet. And this generates another conflict: with more satellites and rockets in orbit, the risk that a fragment of some of them hit a plane is increasingly high. At the University of British Columbia they have proposed to analyze it and have determined that, to anyone’s surprise, the consequences of the clash would be devastating. The problem. Beyond the test rockets, transport of goods and people, something that is causing more and more launching are the satellites that bring the internet to any corner. There are several players in this segment, but Spacex carries the front with its program Starlink. These satellites are sent in rockets that, when they fulfill their function, lose height and return to the planet. Some partially disintegrate and others, to the re -enter the atmosphere without controlthey fall anywhere. The ocean is usually the main receptacle, it is also possible that they fall in urban areas or that, on their way, they clash against a plane. The probability. First of all, tranquility: the risk that these space debris impact an plane is still low, very low. According to The Aerospace Corporation, in 2021 (when they were thrown, but it was not the current fever), that risk was one between 100,000, or 0.001%. The system predicted, taking into account future releases, which by 2035 would rise to seven out of 10,000, or what is equal to 0.07%. It is, as we say, a low probability, but that is there. In the study From the University of British Columbia they have analyzed how all this depends on air traffic density. Taking as an example the traffic of September 1, 2023, and the United States as a area, we can see that, every year, there is a 99% probability that the resentments of rocket bodies occur in green areas, 75% in the yellow, 26% in oranges and 0.8% in red. Las Rojas are the most activity areas, such as the main airports, oranges are large cities and green and green move away from urban nuclei and, therefore, from the agglomeration of airplanes. Long March 5B. Beyond the direct clash of this space scrap against a plane, something whose probability remains exceptionally low, there is another problem: the danger of happening and leads to the decision to cut the airspace. On November 4, 2022, the body of the Long March 5B rocket, 20 tons of weight, re -entered the atmosphere, falling on the Pacific Ocean. All good, but it might not have been like this: the entrance location was the product of chance, since the body of the rocket was abandoned in the orbit and a planned design was not made for the re -entry of the remains. Consequences. The night before the reentry, different surveillance agencies, as well as the European Air Safety Agency, issued reports in which they encouraged national authorities to restrict airspace “in a corridor of at least 70 kilometers and up to 120 kilometers on each side of the estimated reentry trajectory ”of the rocket. Spanish and French authorities complied with this and They closed part of their airspace. As a result, 645 flights were delayed, with an average of 29 minutes per plane. In addition, some airplanes that were in full flight had to return to the origin airport or take a detour. It was the evidence of a lack of planning, anticipation and control over this space scrap. Interestingly, Portugal, Italy and Greece did not make the decision to close, generating other problems in their airports due to the unexpected increase in air traffic due to deviant flights. In purple, the airspace closed by the Long March 5B. In blue, his career and fall Solutions. Unfortunately, although this is a problem that will go more, controlling the reentry of space debris is not something that has an immediate solution. The researchers propose that those responsible for launching rockets also invest in controllable reentry technologies so that they do not enter the atmosphere unpredictably. These technologies include engines capable of re -effective to partially direct the rocket, but also a better mission planning so that the rocket falls into a remote area of ​​the ocean, far from populations and, evidently, air traffic. The problem is that, although the technology is there, they estimate that less than 35% of the launches perform these controlled inputs and, with 2,300 bodies in orbit with an annual increase of between 30 and 40 bodies, the risks will continue to increase. In 2001, the titanium engine coating of the third stage of a Delta 2, with a weight of approximately 70 kg, landed in Saudi Arabia, about 240 km from the capital Obviously, it is also a huge money expense, so achievements such as catch the Starship propeller and the advances of Spacex engineers so as not to have launch and throw rockets They are so important. And a global protocol is also necessary to manage these resentments and make coordinated decisions, not to delegate everything in an aeronautical industry that is not responsible. In the end, it is much more likely that there are alterations in air traffic due to this space garbage than to the clash of one of these remains with a plane, but whenever this probability is not zero, solutions must be contemplated.

Airbus’s hydrogen plane was going to reach the market in 2035. It has now been delayed in the midst of “great” challenges

Airbus wanted to take the me. First commercial plane of the world propelled by hydrogen In 2035. The ambitious initiative continues to exist, only that it is not clear when it will end up materializing. The European aerospace giant has recognized that the project is progressing at a slower pace than expected. As Reuters collects He said that “the development of a hydrogen ecosystem, which includes infrastructure, production, distribution and regulatory frameworks, is a great challenge that requires global collaboration and investment.” One of the most important obstacles has to do with obtaining renewable hydrogen. An ambitious project, multiple challenges The main objective of the hydrogen plane is to reduce air transport emissions, and at this point the Hydrogen production: Obtaining large quantities using renewable energy is still complicated. Green hydrogen needs a lot of investment And a long way to go to be widely profitable. Guillaume Faury, CEO of Airbus, has said in the past that there is a doubt that there is sufficient green hydrogen in the future to boost a large number of commercial airplanes, but the company has continued to boost its plans to reduce emissions, which also include the use of Sustainable aviation fuel (SFA). Airbus has not yet given a new calendar for the project, but the signs are not optimistic. According to the Force Ouvrière union, workers were informed this week that technology has a delay between five and ten years with respect to the necessary rhythm. With this panorama, the objective of 2035 seems increasingly complicated. The aforementioned organization has indicated that the European firm is also evaluating the completion of “Certain subprojects” It is not clear if in addition to the aforementioned challenges related to the alternative fuel supply there are other disadvantages in the development of proposed aircraft. Airbus presented three concepts in 2020. The first, a turbofán with capacity for about 200 passengers and a range of 3,704 kilometers. The second, a more content turbohyl, designed for about 100 passengers and with 1,852 kilometers of reach. And the third, a mixed wing model, also turbophah, with the same figures as the first. The company also contemplated two propulsion systems. On the one hand, the Hydrogen combustionwith gas turbines with modified fuel injectors. On the other hand, a completely electrical propulsion system with hydrogen fuel batteries, which feed electric motors that turn the propellers or plane turbines.

detect a plane at 5,000 meters high

China has been around for a while developing all types of sensors and radars whose characteristics suggest a future very different from the current one. Without going too far, last September They tested a device called LARIDa super radar that was able to detect a gigantic bubble of invisible plasma in the Pyramid of Giza. The latter is something very different, and can change the battlefield. Unprecedented underwater radar. In a secret location 1,000 meters deep, Chinese scientists have developed and tested what points to an unprecedented underwater sensor capable of detecting aircraft at high altitude from the depths of the ocean, representing an unparalleled strategic advance for the People’s Liberation Army (PLA) submarine fleet. To give us an idea, technology managed to identify a fixed-wing aircraft at 5,000 meters above sea levela milestone that no other nation has achieved to date. Such technology, which until now was considered impractical due to the complex acoustic properties of water, could dramatically improve the survivability of submarines against warplanes. antisubmarineequipped with advanced sensors to locate and destroy them. Implications and capabilities. Underwater radar represents a significant strategic advantage for the nation. The reason? Turn the current combat around, allowing your submarines to go from targets to hunters in anti-submarine warfare. Currently, aircraft equipped with advanced sensors can detect and attack submarines without being spotted, but with this new technology Chinese submarines could, a priori, receive early warnings of hostile aircraft and launch missiles from underwater with precision. And there is more, of course. The main technological challenge lies in the fact that most of the sound waves generated by aircraft are reflected from the sea surface, making their detection difficult. However, researchers at the Institute of Acoustics of the Chinese Academy of Sciences, led by Zhang Bo and Peng Zhaohuiemphasize that they have achieved an innovative solution by taking advantage of the multiple reflection of sound waves between the seabed and the water surface, allowing Extend detection range and improve radar sensitivity. System testing and limitations. Apparently, In 2022, China carried out secret tests of underwater radarmanaging to detect a plane 17 kilometers away and, attention, with a margin of error of less than one kilometer. Still, limitations were identified, such as a blind spot when aircraft fly directly over the sensors, as well as a detection range that still needs to be expanded for effective military applications. In this regard, Zhang and Peng continue working on system optimizationalthough they have not revealed recent data. Complement to the military intelligence network. China’s military strategy is based on a multi-layered approach that integrates various detection technologies. Currently, the People’s Liberation Army has a satellite network capable of tracking high-performance aircraft like the F-22 stealth fightersin addition to radar systems on ships and land stations. The new underwater radar would act as a complement, providing redundancy and improving detection capability in hostile environments. Future perspectives. Although the details of this development were kept secret for years due to its military sensitivity, the research team has recently published an article in the journal Acta Acusticaa job where information about the functionality of the system is provided. That said, and as is often the case with innovations of this type, everything indicates that there remains a long road of testing and improvements in operational scope to guarantee its effective integration in real combat scenarios. What does seem abundantly clear is that the innovative underwater detection system marks a paradigm shift in naval warfare, one where, in the absence of verifying it on the ground, It would give China a huge tactical advantagehighlighting its leadership in the development of cutting-edge underwater surveillance technologies.

La Perla arrives in LA with its vibrant rhythmic, feminine and combative fusion

It doesn’t seem to be a coincidence. In recent weeks, we have announced the different avant-garde cumbiera groups that have been visiting Southern California, which seems to indicate the existence of a renewal movement that is not limited to a single Latin American country. And although Son Rompe Pera -who performed at Alex’s Bar in Long Beach after passing through Coachella-, Black Rooster Sound -which was presented at the same Alex’s on December 31- and Karen and The Remedies -which was at the Lodge Room on January 18- came to our shores representing Mexico City, what is coming from the same musical side tips the balance towards the original territory of the genre, that is, the Colombian nation. The most immediate corresponds to the show that will be offered on March 9 at The Echo (1822 W Sunset Blvd., Los Angeles, CA 90026), and which will be headed by La Perla, a Bogota combo made up of Karen Forero, Giovanna Mogollón and Diana Sanmiguel who, despite respecting traditions, has chosen to combine them with modern contributions that reflect her own identity. Placing themselves within the topic of “new Colombian music,” the members of the combo claim to have been in contact for a long period of time with the teachers of the school they practice through the informal folklore meetings that take place in their city, and which are usually called “wheels”. After winning the prize for the amateur category at the National Bagpipe Festival that takes place on the Colombian coast thanks to the interpretation of classical pieces, and having thus become the second all-female band to triumph in the prestigious contest, Forero , Mogollon and Sanmiguel began to create their own songs, maintaining the percussion format (using drums and seeds) and adding elements of hip-hop and beatboxing. The preparation was long, but finally, in 2022, after publishing several singles, they managed to release their first album, “Callejera”, which also includes contributions from merengue and champeta, and which, unlike cuts of rural origin, cater to urban themes that, in many cases, are connected to social interests worthy of consideration. Another photo of the band. (Maria Alejandra Villamizar) That is the case of “Bruja”, which achieved notoriety after being included in the Netflix original series “Siempre Bruja” (“Always a Witch”), and which seems to speak of the unfair persecution suffered by women who have decided challenge conventional norms; from “El Sol”, which is dedicated to the farmers who are experiencing hardships in our countries, and from “La Selva”, which demands the respect that the Amazon deserves. It is, in the end, a proposal that is as vibrant on the rhythmic and vocal level as it is combative on the level of messages, and that you will be able to appreciate live if you attend the aforementioned concert by The Echo, where the three Bogota natives will share the stage with Susobrino, an electronic artist and DJ of Bolivian descent who appeals to the sounds of his ancestors in order to generate a unique style. The next visit to the coffee country that is going down similar paths is that of Los Piranas, the celebrated instrumental supergroup made up of Eblis Alvarez (from Meridian Brothers), Mario Galeano (from Frente Cumbiero and Ondatrópica) and Pedro Ojeda (from Romperayo and Sidestepper). This presentation will take place on April 11 at The Lodge Room (104 N Ave 56, 2nd floor, Los Angeles, CA 90042), and there will be an opportunity to talk about it in more detail.
