Another Boeing (BA.US) plane accident injured 50 people, which has dropped by 26% since the beginning of this year.

  

A Boeing (BA.US)787-9 Dreamliner of South American Airlines had technical problems on the way from Sydney, Australia to Auckland, New Zealand’s North Island on the 11th, causing 50 people on board to be slightly injured.

It is reported that the Boeing 787-9 Dreamliner of Chile’s South American Airlines departed from Sydney to Auckland in the afternoon. On the way, due to technical problems, the passengers on board suddenly shook violently, causing instability, and 50 people were injured, one of whom was seriously injured. After the plane arrived in Auckland, 13 people have been taken to hospital for treatment.

According to foreign media reports, South American Airlines confirmed that the aircraft number LA800 was violently shaken during the flight due to technical problems, which affected some passengers and crew.

The accident involved a Boeing 787-9 Dreamliner, and it is still unclear what the technical problems referred to by South American Airlines are. However, the United States Federal Aviation Administration pointed out last week that there was a problem with the anti-icing system of Boeing Dreamliner, which might affect the engine vent, causing the aircraft to freeze or malfunction when flying at high altitude.

Last week’s report pointed out that the problem of anti-icing system is being dealt with according to the government’s "airworthiness directive" standard process, which indicates that the problem may not be serious enough to require grounding.

Recently, Boeing’s planes have had frequent accidents, the most noticeable of which is the embedded door of the Boeing 737 MAX 9 of Alaska Airlines (ALK.US) that suddenly fell off in the sky. Boeing’s share price has plummeted by more than 25% this year, after it was reported that the US Department of Justice had launched a criminal investigation into a 737 Max aircraft door falling off in January.

The company’s share price once fell by 4.4% in new york on Monday, the biggest intraday decline since January 25th. Alaska Airlines, as the operator of the 737 Max 9 aircraft, confirmed the report on the investigation last weekend.

According to foreign media reports, as part of the investigation, the federal prosecutor has convened a grand jury. As of Monday’s close, Boeing closed down 3.02%, making the decline this year reach 26%, the worst performance among the Dow Jones Industrial Average. After a series of accidents and manufacturing errors were exposed, the crisis surrounding the American aircraft manufacturer and its best-selling 737 passenger plane was escalating.

After the Alaska Airlines incident on January 5, Boeing faced more and more scrutiny from lawmakers, regulators and even passengers. US Transportation Secretary Pete Buttigieg told Fox News last Sunday that the FAA will be very strict in dealing with Boeing and any regulatory issues.

Today’s football recommendation analysis score forecast Bologna VS Lazio La Palmas VS Atletico Madrid

In the 11th round of Italian first-class football league, Bologna played against Lazio at home. Bologna’s scoring efficiency is good this season, but there are many draws. In the last round, Sassuolo was tied, and all the away games were tied this season. Bologna has been unbeaten in the last 9 games, with 3 wins and 6 draws, and all three victories were won at home. Lazio beat Fiorentina 1-0 in the league on Tuesday morning, and Inmobile scored a 90-minute penalty to help the Biancocelesti score all three points. At present, Lazio has won three consecutive victories in the league, while 2 wins and 3 losses in the away game, and defeated Sassuolo as a guest to end the two-game losing streak in the away game. This season, the Biancocelesti’s attack is average, with only 13 goals scored in 10 rounds and 12 goals conceded.

Lazio won 1 win and 1 draw against Bologna last season and remained unbeaten. However, in four consecutive seasons, Lazio only scored 2 draws and 2 losses without winning, and even failed to score in the last three games. The data of this game is insufficient for Lazio’s support. After all, as a traditional strong team in the league, the tie is not easy to overestimate when its reputation and status are dominant.

Therefore, the home team, Boluo, is always in Asia, and it is expected that the match will be more exciting than the match 1 midfielder. The right pair is in charge. The performance in the field is stable and has the strength advantage, while Lazio needs to show better performance in the away game to continue its unbeaten record.

Las palmas beat Manakol 3-0 in the last round and won two consecutive victories, in good shape. The team has a strong offensive ability, scoring only 9 goals in the past 5 rounds, but the defensive quality has improved, losing 4 goals in the past 5 rounds. This season, it has achieved 4 wins, 2 draws and 5 losses, ranking 10th in the league. Sandro ramirez, Fabio Gonzá lez and others were plagued by injuries or missed the game. It must be difficult for this field to face the former bitter Atletico Madrid.

Atletico Madrid beat Aravis 2-1 in the last round, and the team’s morale is like a rainbow. So far this season, it has achieved 8 wins, 1 draw and 1 loss, and its performance is excellent, ranking third in the league. In the last five rounds, he scored a total of 12 goals, averaging 2.4 goals per game. The quality of the team’s defense is very high, and he lost 6 goals in the past five rounds. French striker Gleizman scored 7 goals, and Morata scored 6 goals, which was the main scorer of the team. At present, Victor vitolo, Depe, Mandawa, etc. in the team are plagued by injuries or absent from the game. Atletico’s players can always adapt to different competition environments and play well. Their tactical flexibility and adaptability enable them to always have an advantage in away games.

To sum up, I think Atletico Madrid will win on the road. Although we know that the away game is full of challenges, Atletico’s strength, experience and tactical flexibility all indicate that they will win this victory. I believe they will show their advantages in the competition and finally win.
