Every day, thousands of flights travel around the world. Most people find it comfortable to fly.
Walk through the sky, admire the magnificent mountains and rivers, and reach your destination when you land.
Sometimes special fares are even cheaper than other means of transport, and many people are used to flying.
However, due to the peculiarities of the aircraft, an accident can be catastrophic.
Few people have learned more about aviation accidents, but in today's era when air travel is becoming more and more convenient, we need to know more —

The documentary "A Fall: The Boeing Investigation" documents two major aviation accidents that occurred in 2018.
Oscar-nominated filmmaker Lori Kennedy exposed how the greed of the aviation company led to the crash of two Boeing 737 MAX planes in just five months.
There's an old saying in aviation: "If it's not a Boeing plane, I won't sit." ”
Boeing has a very storied history and is one of the largest manufacturers of civil and military aircraft in the world.
Airliners in many countries are made by Boeing, and boeing aircraft were once a symbol of safety.
Every moment, 10,000 Boeing planes fly in more than 150 countries.
Until 2017, there had been no crash of a major Boeing airliner anywhere in the world.
In October 2018, however, lion air 610, which belongs to Indonesia, disappeared from radar a few minutes after taking off from Jakarta.
The all-new Boeing 737, carrying 189 people, crashed shortly after takeoff.
All the crew were killed and none survived.
It was a brand new 737 MAX aircraft produced by Boeing, an upgraded version of the 737 aircraft.
It crashed into the ground at high speed, which can be said to be very tragic.
The following is the simulation screen -
The accident was a strange one, the weather was nice that day, the crash site was close to the airport, and it was a brand new plane.
After finding the black box, the cause of the accident gradually surfaced.
The flight data logger showed that the left angle of attack indicator had failed after takeoff.
In addition, there is something unknown that constantly presses the nose of the aircraft downwards.
Although the pilots were fighting and trying to pull the plane back, the nose was pressed against the ground until it crashed...
Dennis Millenberg, Boeing CEO at the time, simply responded: "We can't comment on the survey. ”
However, Boeing said behind its backs that "this would not have happened if it were an American pilot", implying that the level of responsibility for the accident was limited among Lion Air's Indonesian crew members.
Boeing even investigated where Indian captain Bafye Suniga received his flight training.
Ironically, however, he trained in the United States.
Finally, Boeing finally released a statement saying that the Maneuverability Enhancement System (MCAS) of lion aircraft was incorrectly started.
The announcement was in an uproar, and the pilots said they had never heard of the MCAS system.
It turns out that this MCAS system is connected to the angle of attack sensor, and its role is to press the nose down.
Once the system is triggered, the captain has 10 seconds to turn off mcAS.
In the Lion Air crash, an angle-of-attack sensor was broken, the MCAS system was incorrectly activated, and the pilot did not shut down the system in time.
The nose of the machine is pushed downwards until it crashes.
Boeing believes that the responsibility for the accident lies in the crew's failure to shut down the MCAS system in time.
In fact, however, Boeing never told Lion Air pilots that such a system existed.
It did not tell them that once the system was triggered, there was only 10 seconds to escape.
What's next for Boeing?
They said they would fix the problem after 6 weeks, and other than that, nothing would be done during those 6 weeks.
In other words, this aircraft with serious safety hazards continues to fly around the world.
And Boeing insists that the 737 MAX aircraft is safe.
The punch came so quickly that another crash occurred shortly after.
On March 10, 2019, 19 weeks after the Lion Air accident, an Ethiopian Airlines flight crashed shortly after taking off from Addis Ababa, killing all 157 passengers and crew on board.
When the families of the victims arrived at the scene of the accident, they saw debris from the plane and the messy luggage of passengers, as well as a hole in the ground that had been knocked out by the plane, which crashed straight into the ground at a speed of 800 kilometers per hour.
The accident was the same model as the plane that Lion Air crashed, and the crash site was also close to the airport, and the weather was not bad.
Exactly the same tragedy, happening again.
The 737 MAX aircraft was Boeing's best-selling airliner, but it had two crashes in just five months.
What's even more frightening is that many of the world's major airlines are using this new type of aircraft, with hundreds of aircraft already in service and thousands already on order.
Some people began to call for the grounding of the aircraft.
However, Boeing still insists that the 737 MAX aircraft is safe.
On the day after the crash, only China grounded the aircraft of this model.
This has triggered grounding in other countries around the world, including Australia, New Zealand, Malaysia, Singapore, France, Germany, Italy, the United Kingdom, Ireland, the Netherlands...
The accident investigation continued, with investigators finding lifting screws at the scene of the accident in Ethiopia.
The role of the lifting screws is to manipulate the aircraft stabilizer, while the found lifting screws are in a position that is fully downward.
This further confirms that the cause of the accident is related to the Maneuverability Enhancement System (MCAS).
At this point, the then US President Trump suspended the flight.
All 737 MAX8 and 737 MAX9 flights with the Maneuverability Enhanced System (MCAS) were grounded.
It also became the only aircraft in history to be grounded by a U.S. president.
But even after MAX planes were grounded, they had to fly to designated storage facilities, and pilots who learned the truth were reluctant to fly the distance anymore.
At the same time, the families of the crash began to demonstrate in Washington, D.C., and some of them lost almost all of their loved ones as a result of the crash.
The two crashes, which killed 346 people in five months, became the largest investigation in the history of the U.S. Transportation Infrastructure Commission.
Boeing, on the other hand, once again shifted the blame for the accident to the Ethiopian pilot, believing that the crash was due to the pilot's improper operation.
Because after the Lion Air accident, they have informed all pilots of the operating instructions of the Maneuver Characteristic Enhancement System (MCAS).
To this end, Boeing launched a huge public relations campaign.
They also ask ethiopian pilots to show pilot qualifications and proof of training.
However, as the investigation deepened, more striking facts surfaced.
Investigators discovered that when the accident occurred, the Ethiopian crew not only realized the activation of the maneuverability enhancement system, but also did it according to Boeing's instructions, shutting down the maneuverability enhancement system.
But the plane still did not escape the crash.
At this point, we have to wonder how the world's largest passenger aircraft manufacturer could be so outrageous.
Boeing's success, of course, depends on technical strength.
The former Boeing company did pursue safety first, and the company tended to flat management, and employees found that problems could be raised directly without fear of being fired.
The working atmosphere was very harmonious, and the former employee described it as a big family.
Until 1996, Boeing merged with McDonnell Douglas.
McDonnell Douglas brought their business plans into Boeing and decided that the most important thing was to make money.
Wall Street demanded a return on profits, and they wanted Boeing to give them back like a big industrial company.
Once upon a time, Boeing's corporate culture was to ensure quality and safety, and not to take shortcuts.
In order to win the increasingly fierce competition in the passenger aircraft market, the tradition of valuing safety has compromised to money.
All aircraft had to reduce costs, the number of workers was drastically reduced, and more value was created with fewer resources.
In addition, McDonnell Douglas pursues the humane society, and the opinions of technicians are repeatedly not taken seriously. Technicians have accelerated production, but quality inspections have been repeatedly relaxed.
The predecessor of the 737 MAX aircraft that crashed was the Boeing 737, and in order to win the market competition, Boeing did not have time to develop a new type of aircraft, and it was modified on the basis of the 737.
The fuselage is getting longer and the engine is getting heavier.
Since the engine device is in the tail, in order to prevent the tail from falling too much, the MCAS system is installed, and once it is touched, the nose will be pressed down.
The reason for the crash of both planes was because the MCAS system was inexplicably touched.
And once touched, the pilot has only ten seconds to close it, and more than ten seconds can only wait to die.
Pilots don't know about the MCAS system because if MCAS is emphasized as a new feature, pilot training needs to be scheduled, and the cost goes up.
Boeing assured airlines that their pilots would not need simulation training.
The reason is that this aircraft is not much different from the old model 737.
Unfortunately, just a year before the crash, Lion Air was asking Boeing if it needed extra training.
Boeing's response was that there was absolutely no need for flight simulation training to fly the MAX.
They even mocked in the mail, Lion Air's caution.
Boeing has indeed been a commercial success, and they have sold more than 5,000 MAX aircraft.
The product brought Wall Street's financial performance to levels never seen before boeing, and stock prices soared.
The 737 MAX will be Boeing's main source of revenue for decades to come.
The good days ended with a loud bang from Lion Air in October 2018.
As we all know, crashes are often so tragic that it is difficult for anyone to survive a disaster of this magnitude.
The two accidents in the documentary "Plummeting: The Boeing Investigation" could have been completely avoided, not as a human-majeure accident, but as a problem with the system itself.
The pilots only had ten seconds to escape without training, and the Lion Air pilots didn't even know these ten seconds...
It's hard to imagine the world's largest airliner manufacturer doing such outrageous concealment for profit.
This documentary reveals an obvious truth:
Speculating on matters where human lives are at stake will not lead to good results.
After all, life is more precious than anything else.
