The models involved were grounded by the whole United States
Boeing claims to strive to resume early flightJaipur Wealth Management
On January 5, local time, flight 1282, Alaska Airlines from Portland, Oregon to Portland, Oregon, soon had to return to land after taking off.The air exploded, causing hundreds of passengers in the cabin to be exposed to external air.
After the accident, hundreds of Popular 737 MAX 9 aircraft have been grounded by regulatory agencies, including the United States, Latin America, Turkey, and the European Union.
Boeing’s stock price was significantly lowered at a price of $ 228 per share on January 8th. Compared with the closing price of the previous trading day, it fell more than 8%.On the Frankfurt Stock Exchange, Boeing’s stock price decline is also close to 8%.
The Federal Aviation Administration said on January 6 that it has ordered the temporary 737 MAX 9 aircraft operated by the United States Airlines or operated in the United States, and requires various airlines to check immediately.According to officials of the bureau, the order affects 171 aircraft in the United States, of which United Airlines and other companies are the main buyers of the Boeing model.The National Transport Safety Commission also conducted an investigation on the accident.A preliminary survey showed that the aircraft used by Alaska Airlines had a warning light on the previous flights, indicating that there may be a problem of supercharged in the cabin.
Boeing stated that the decision of the Federal Aviation Administration was fully supported and "deeply regrets" the incident.Boeing added that its technicians are assisting the investigation and hoping to resume the 737 MAX 9 model as soon as possible.
In March 2019, a crash in Indonesia and Ethiopia died of 346 people, and multiple national aviation regulators successively forbided the most popular passenger plane in Boeing 737 MAX.It was not until two years later that this model was lifted in major markets such as the United States.Boeing hopes that this lifting of the ban does not need to wait for two years, but this will depend on the investigation and processing progress of the authorities of various countries.
The drop door was picked up in the resident’s backyard
Investigators "Changshu breath"
Jennifer Hormadi, chairman of the National Transport Safety Commission, revealed that a school teacher in the Sida Mountain community in Portland, Oregon found the emergency door of the flight involved in his flight on January 7.Homanidi said that she and her colleagues felt "very happy and relaxed and relieved" about the foundation of the cabin door, because the emergency cabin door was a "key missing part" for determining the cause of the accident.
"Our structural team needs to check all the parts on the door, check the marks and certificates, check any changes in the paint, and the specific shape of the discovery of the door. This can tell us many things that happened in the past."New Delhi Stock Exchange
Hoomy said that a pilot who was investigated said that he heard a loud noise at the time, and then various working forms "flying in the sky" in the cockpit, and the co -pilot lost his headphones in the chaos."The communication of the unit became a serious problem … The scene at that time could only be described as chaos."
However, the cabin voice recorder involved in the case did not capture any data, because the data at the time of the incident had been covered, and the recorder now automatically covers the data every 2 hours.Homani called on regulators for mandatory requests to modify existing aircraft, equipped with a recorder that can capture 25 hours of data.
Homani said that Alaska Airlines made a decision after receiving the aircraft warning light warning, limiting the aircraft to fly from the water long -distance flying to Hawaii so that they could quickly return to the airport when needed.This decision later made the aircraft quickly settle down after the accident.
Alaska ’s previous questions about the lighting of the alarm lights said that aircraft supercharged system alarms are common in commercial aviation operations of large aircraft.The airline said: "Under any circumstances, we will comprehensively evaluate and resolve them based on the approval maintenance procedures. Our operation fully meets all applicable US federal aviation regulations."
Alaska Aviation added that the internal policy of the company stipulates that aircraft with multiple maintenance records on certain systems are limited to long -distance water flights, and the Federal Aviation Administration has not asked for this.
The iPhone screen dropped by passengers is intact
Or it is related to air resistance and grass buffer
On January 7, a user named Sean Bates in Portland, Oregon posted on social media that he was walking on the road when he was walking on the road of Barnes Road near the Highway 217 and found an iPhone.In the bushes.The mobile phone was still in the flight mode at the time. The battery power was only half, and the screen was intactAhmedabad Investment. "There was no scratch." The cover of the mobile phone showed the $ 70 receipt of the two consignment luggage of Alaska Airlines 1282.
Bates said that after calling the National Transport Safety Commission, he confirmed that the phone was the second phone that the phone was discovered by the phone.
Bates wrote on Twitter: "I did not expect that this phone fell from 16,000 feet (nearly 5000 meters) at a high altitude and could be preserved so complete."
Duncan Watz, a postdoctoral researcher at the Institute of theoretical Astronomical Physics at the University of Oslo University, believes that although the smartphone screen has become more and more strong, the "strong" of this iPhone is likely to be based on physical principles.
"The basic answer is air resistance. What violated intuition is that the iPhone fell from the sky will not move so fast due to air resistance."
Duncan explained that any object that landed from high to the earth would reach a "terminal critical point"Hyderabad Wealth Management. Due to the resistance of the air in the atmosphere, the gravity could no longer accelerate it.
"If the screen of the mobile phone drops facing the ground, it will generate a lot of resistance, because the mobile phone will roll greatly and be affected by the wind, which will essentially generate a upward rise."
Duncan pointed out that if the phone falls on a stone or a hard sidewalk, it will definitely be damaged, but it will eventually fall on the grass, and the grass and leaves can buffer its drop."If the phone falls on the front of the phone on the grass, its speed will change from about 30 miles to a static surface on a relatively comfortable surface, which is much smaller than I step on the phone screen."
Apple’s user guidelines do not specifically explain how high the iPhone mobile phone can withstand a high position drop, but there is a saying: "Please be careful to handle the iPhone., Burning, piercing, squeezing, or contacting liquid, iPhone and its battery may be damaged. "
