The mysterious incident with the Boeing 747



June 24, 1982, aircraft Boeing 747 British Airways, made one of its longest flights on the route London—Bombay—Madras—Kuala Lumpur—Perth-Melbourne—Auckland. On-Board there were 248 passengers and 15 crew members.

The first oddities arose after 20:40 over the Indian Ocean, to the South in 150 km from the island of Java. At an altitude of 11300 meters. Passengers began to notice oddities. Smoke appeared. At first, it did not cause concern, because in those years Smoking was allowed onboard the aircraft. But then the smoke became denser and there was a smell of sulfur. Flight attendants rushed with fire extinguishers to look for a source of ignition. The smoke was everywhere, and the source could not be found. The aircraft commander turned on the “Fasten your seatbelts” sign. At this time, the crew and passengers saw a strange and strong glow of the wings of the aircraft. And from the engines burst out fiery plumes of blue and purple colors.

It was like the famous Lights of St. Elmo. But where do they come from? The lights of St. Elmo were first seen by sailors. Suddenly, the tops of the masts are lit up with a flickering bluish glow. In the Middle Ages, a legend was born in Europe. Saint Elm died during a storm on the deck of a ship. Before his death, he promised that from the next world he would give signs of an impending disaster, and these signs would be dancing magic lights. These discharges of atmospheric electricity can damage electronics.

The commander's first thought was about the glaciation of the ship, but the weather conditions did not give such an opportunity. Just in case, the commander turned on the de-icing system. The second thing that was thought was thunder lightning. But the weather locator showed clear skies. The situation worsened every minute. At 20:42, engine No. 4 stopped. The crew immediately turned off the fuel supply and put the fire extinguishing system in a state of readiness. After a minute, engine No. 2 stopped. The crew stops supplying fuel to it, and the remaining engines No. 1 and No. 3 immediately stop. All four engines freeze. The plane flies in silence embraced by the lights of St. Elmo. The crew does not have any clue about what is happening. Passengers in a panic. At this moment, the commander of the ship makes a message to the passengers that they will remember for life. “Ladies and gentlemen,” this is the captain speaking. We had a small problem on board. All four engines stopped. We are doing our best to launch them. I hope this does not bother you too much.” Well, what's the trouble? Only quiet horror and panic! The aircraft, although jet, has aerodynamic qualities. In Boeing 747-200, these qualities allow you not to fall immediately, but to lose altitude at a speed of 1 kilometer per 15 kilometers of flight.

The crew quickly estimated that the flight would last another 23 minutes and they would fly away at a distance of 167 kilometers. It was enough to reach the airport in Jakarta. At 20:44, the second pilot reported that all four engines stopped on the plane. However, the dispatcher in Jakarta did not understand the message and decided that only one-fourth engine had stopped. Negotiations were heard by a pilot of a nearby Garuda Indonesia airline who was able to transmit the correct information to the dispatcher. Despite the inclusion of an emergency beacon, the dispatcher in Jakarta could not see the plane on his radar. On the way between the plane and Jakarta stood a mountain range 3,500 meters high.

The mysterious incident with the Boeing 747

The commander of the ship had a question: take a chance and try to fly over the mountains, or turn around and board the water in the Indian Ocean. But how to get on the water? No one even imagines whether this is possible. There is nothing but the most general recommendations. While the commander was thinking, the co-pilot and flight engineer unsuccessfully tried to start the engines. At this time, the pressurization system of the cabin is turned off, and the pressure begins to drop rapidly. Oxygen masks fall from ceiling panels. But the co-pilot had a broken mask. Seeing the co-pilot losing consciousness, the commander lowers the plane to a height where you can breathe. Height 4100 meters. There were seconds to the ridge, it was necessary to turn around. Suddenly engine No 4 starts. The commander uses this to reduce the rate of fall. Suddenly engine number 3 starts. Followed by all the others. The plane immediately gains height and overcomes the mountains. Again a strong glow appeared, and engine No 2 stopped again. The mountains have overcome at the critical height of 3700 meters. Landing in Jakarta was extreme. Instrument landing was not possible. In addition, the automatic landing system at Jakarta Airport did not work. The windshield mysteriously lost transparency. After two small gaps, the second pilot monitored the distance from the strip, and the commander monitored the height. Landing lights of the aircraft also did not work. Moreover, the lights of the landing strip shone in an opaque windshield. However, the crew managed to land the plane. After the joy of a successful landing subsided, wanted to quickly find the cause of this unusual incident. But seeing the plane outside in the morning, the mysteries only increased. The plane seemed to be rubbed with sandpaper. In places, there was no paint at all. All the stickers got off. No one could explain. Why did all the engines stop? The motor manufacturer Rolls Royce took them off the plane and sent them to London for examination. The engines inside were badly scratched and clogged with fine dust. The blades are covered with a sintered crust. After the chemical analysis of solid particles, it turned out that it was volcanic ash. The culprit of the flight accident was found. On the night of the flight, an eruption of the Galunggung volcano occurred 160 kilometers from Jakarta. In those years, this volcano erupted quite often.

But never did these eruptions interfere with flights. This time, the ashes rose to a height of 15 kilometers, and the wind drove the ashes towards the plane. Solid particles from friction on the skin of the aircraft caused a glow. And getting into the engine, the ash was baked and deposited in the combustion chamber and on the nozzles. When the plane crashed and left the ash cloud, the engines started again.

The mysterious incident with the Boeing 747

This was the first case of the impact of volcanoes on an airplane in the history of world aviation. After that, the Rules of Meteorological Support for Flights were amended. From now on, they began to take into account volcanic activity as a potential threat to flights.

      Square Enix published a translation of the session of answers to investors ' questions about its financial results in the first half of the current fiscal year. Chief Executive Yosuke Matsuda confirmed that sales of "The Avengers" were below expectations and that the action role-playing movie has not yet paid off its production budget.

      Earlier it became known that Square Enix sold only 60% of the planned circulation of "The Avengers". It is estimated to have a budget of between $170 million to $190 million, with initial sales of only about 3 million copies. Because of this, the company's HD division lost approximately $ 62 million in the second quarter.
      Matsuda noted that if The Avengers hadn't been released last quarter, the HD division would have remained in the black. However, the losses were caused not only by the non-recouped development costs, but also by the marketing campaign, which suffered due to delays caused by the coronavirus pandemic.
      That being said, Square Enix still intends to make it profitable with post-release support. Last week, the developers announced that Kate Bishop will appear in The Avengers on December 8th.

      At a recent panel dedicated to "Rick and Morty," the authors revealed that they are already working on the seventh season of the animated series.
      According to writer Dan Harmon, he can no longer clearly track plot milestones — he even threatened to unwittingly reveal spoilers for the fifth or sixth season. Harmon also hinted that the" space version " of Beth will return in the future and somehow affect the overall plot.
      Previously, the Adult Swim channel swooped in on 70 episodes of the project from the creators, and so far the show has just reached the season 4 finale - this happened at the end of May.
      There is no exact date for the premiere of the sequel yet.

      In a recent interview, Zack Snyder said that for his version of "Justice League" in total, no more than 4-5 minutes were completed.
      Specifically, we are talking about new scenes, for which the director attracted most of the original cast. The numbers were so small because all the other material needed to complete the tape was already in the hands of the director - it only needed to be finalized. Simply put, the film's running time will still be four hours.
      He also revealed that this time there was no "focus group", and the tape will be made without any interference with the author's vision. By the way, in his version of the Joker, to the image of which Jared Leto returned again, will be slightly different from the image from "Suicide Squad".
      Snyder's Justice League will premiere on HBO Max in 2021.

      Distortion of science for political and economic ends has prevented the allocation of needed resources to stop the spread of dangerous pathogens. This places all of society as a whole at risk, but exacting an insufferable toll of death and disability on our front-line healthcare workers, along with our most vulnerable populations. COVID-19 has demonstrated how dangerous this scenario has become.

      We have seen the United States top officials publicly flaunt the wearing of masks and use substandard infection control practices.  A super-spreader event was even created at the White House’s Rose Garden when rapid testing was used to prevent the spread of SARS-CoV-2. This type of test is known for high false negatives especially with trying to detect asymptomatic carriers. And a security guard for the president was seen wearing an N95-mask with an exhalation value, a setup for spreading the disease.
      There also have been reports that the federal government has impeded or mitigated CDC recommendations for cruise ship No-Sail orders, and to pressure the CDC regarding school openings.  Having consistent scientifically based messaging on a national level is of utmost importance. The messaging in the United States can be characterized as nothing short of bizarre.
      The CDC has flip-flopped on guidance regarding the use of masks on public transportation, the testing of asymptomatic carriers, and was late to stress the importance of spread with viral aerosols – too many of our buildings are not healthy. Significant infrastructural changes are needed to allow for proper social distancing, increase in ventilation, and air sanitization. Infrastructure upgrades are expensive and so far the United States does not have the political will to actualize these changes.
      Needless to say, it is a warning that the abandonment of scientific evidence-based recommendations has all but stymied effective public health responses in the United States.
      Health Care Worker and Patient Safety is of Paramount Importance
      One of the worst aspects of the United States’ response is the failure to provide adequate personnel protective equipment (PPE). The United States’ federal government has not invoked the Defense Production Act to assure an adequate supply of N95-masks for our workers. These masks require a key ingredient ‘melt blown textile’ which is difficult to manufacture. Relying solely on the free market is ill-advised since, similar to the N1H1 pandemic, industry is reluctant to retool for manufacture when they may not recoup their startup costs. This reluctance has its roots in the ideology and the desire of leaders not to create excess mandates and government overreach.
      Some feel the delay in recognition of aerosolization as a major mode of spread of SAR-CoV-2 was related to the paucity of N95-masks and the desire not to alarm workers. As of this writing, N95-masks are still in short supply.
      The impact that this lack of basic protective gear has had may never be known, for no one is counting SARS-CoV-2 infections and deaths in front-line workers.  A lack of mandatory reporting of work-related illness has resulted in incomplete reporting on healthcare personnel; the number of healthcare workers who died from COVID-19 could be between 752 to above 4000. The bottom line is, we need to do better.
      We have stressed in the past the importance of establishing a surveillance system and regular screening of healthcare workers for endemic dangerous pathogens and those pathogens which have frequent outbreaks in a facility, including pathogens CRE, Clostridioides difficile, MRSA, and SARS-CoV-2.
      Healthcare workers also need to have an economic and healthcare safety net for both themselves and their families. Paid sick leave is of paramount importance, since it is not ethical to have a healthcare worker making the untenable choice between the safety of patients and placing food on their family’s table.  Acquisitions of dangerous pathogens that occur during an outbreak or pandemic should qualify the worker for presumptive disability.
      Additionally, no one is counting patients who contract COVID-19 in hospital settings. The U.S. Department of Health and Human Services’ definition for a SARS-CoV-2 hospital-acquired infection is unfortunately next to useless; “Total current inpatients with the onset of suspected or laboratory-confirmed COVID-19 fourteen or more days after admission for a condition other than COVID-19.” Unfortunately, this definition is next to useless.
      For many patients, the greatest chance of catching SARS-CoV-2 is on the day of admission, due to being placed in a freshly turned over room and possibly going through the emergency room for initial treatment. Thus it is unlikely that few SARS-CoV-2 HAIs will be captured. The most accurate metric would be a diagnosis of SARS-CoV-2 acquisition which would occur 5 days after admission, including those which present after discharge. This metric would balance false positive and negative results and give a much better estimate of overall system performance. This mitigation of SARS-CoV-2 data is reminiscent of past pandemics where countries have a long history of hiding the numbers, as opposed to reporting them and correcting the problem.
      The Need to Take Care of Disparate Populations, Even the Elderly
      Initially, the virus emerged in the northwest region of the United States and devastated Nursing Homes where infectious disease regulations were all too lax. In 2019, the CDC attempted to strengthen infection prevention in nursing homes by enacting the strategy of Enhanced Barrier Precautions.. ‘Enhanced’ a  deceptive word, since these precautions are less stringent than Contact Precautions (these precautions were being advocated for the control of the CDC’s ‘Urgent Threats’ of carbapenem-resistant Enterobacteriaceae (CRE) and Candida Auris and can also be applied to patients colonized with MRSA). Recommendations for Enhanced Barrier Precautions state: “Residents are not restricted to their rooms and do not require placement in a private room.”
      Enhanced Barrier Precautions allow carriers to participate in nursing home activities and only require healthcare workers to implement contact precautions for high-risk activities, but even low-risk activities, such as passing meds, occur so frequently that one would expect frequent healthcare worker contamination.
      These precautions do not appear to be based upon how the MDRO spreads, but instead on avoiding more stringent and resource-intense strategies.
      Such strategies would include: Healthcare worker screening and availability of abundant PPE, along with determining the patient’s microbiome, and if dangerous pathogens are present, decolonization, and as a last resort cohorting patients with similar pathogens in dedicated facilities. Pathogens do not care about politics or the needs of the individual, they are genetically programmed to spread.
      Dangerous pathogens are genetically programmed to spread. Strategies need to be based upon the pathogen and not the political expediency of our leaders or to lessen the economic impact on our healthcare system. The COVID-19 pandemic has taught us the need for public support and embracement of scientifically based public health strategies to stop the spread of dangerous pathogens (proper building ventilation, widespread testing, social distancing, wearing masks, and hand hygiene). These strategies can be expensive to implement and may cause a severe short-term economic burden but are the fastest path to a full economic recovery.
      Whether one deals with MRSA or COVID-19, screening, and decolonization or self-isolation of healthcare workers is of utmost importance. Their health, the health of their families along with their patients depend upon it.

      Flax seeds are an amazing superfood that combines a huge variety of different nutrients and is useful for all body systems. Even in ancient Greece, a decoction of Flaxseed was used as an anti-inflammatory agent, and for more than two thousand years, doctors have strongly recommended adding it to the diet. What is so useful flax seeds and how best to use them in food, we tell in our material.

      What are the benefits of flax seeds?
      Flax seeds contain the plant compound linamarin - it evenly envelops the walls of the stomach, creating a protective film on it that prevents harmful toxins from being absorbed, and protects the stomach mucosa from ulcers and gastritis. In addition, the high concentration of omega-3 and -6 fatty acids in flaxseed significantly increases the elasticity of blood vessels and heart muscle, strengthens them, and helps in the prevention of cardiovascular diseases. Even if you don't have heart problems right now, regular consumption of flax seeds reduces the risk of them appearing in the future.

      Flaxseed is a source of antioxidant compounds. They protect body cells from free radical damage and have powerful anti-inflammatory effects. Antioxidants are the real elixir of youth: they nourish the skin from the inside, prevent the signs of aging and hyperpigmentation and protect the skin from the harmful effects of ultraviolet rays.
      Flax seeds are rich in magnesium and phosphorus, which are essential for the proper functioning of the brain and nervous system. They increase concentration and performance and improve memory. A number of active substances in flaxseed strengthen bones, muscles, and tendons, prevent respiratory diseases, and restore the acid-base balance of the body.
      What's more, flax seeds are essential in your diet if you are looking to lose weight. They help burn visceral fat, and due to their high nutritional value, they provide long-term satiety and significantly reduce the risk of overeating.

      How to add flax seeds to your diet?
      The most important thing: it is useless to add whole flax seeds to food - the hard shell of the seed is beyond the strength of our stomach, which means that not a single nutrient will be absorbed by the body. The seeds can be crushed, or they can be soaked in warm water for 1-2 hours (then the shell will become soft and easily digested, and useful substances will enter the body).

      Further, in chopped or soaked form, flax can be added anywhere - here you are limited only by your imagination. Flax seeds are a great addition to your morning porridge, smoothie, or avocado toast. They can be sprinkled on salads, vegetables, and meat dishes, added to cream soups and stews.
