Today, Sunday, the second black box of the ill-fated East China Airlines plane that crashed with 132 passengers was found, according to the China News Agency.

The agency quoted the Relief Operations Command Center as saying that on March 27, the second black box of flight MU 5735 of the East China Company was found, and it contains flight data such as speed and altitude.

It was confirmed that all passengers on board the "East China" plane that crashed last Monday on a mountainous plateau in Wazhou, southern China, were killed, according to the Chinese Civil Aviation Authority on Saturday.

Dozens of families have been waiting for days for news of the fate of those who boarded the plane, while rescue teams were scanning the forested slopes extensively in search of wreckage and possible survivors of the plane crash Monday near the city of Wazhou.

Determine the causes

On Wednesday, one of the black boxes of the stricken plane was found, and it will take several days to analyze it.

The crash of this plane is the worst accident in the aviation sector in China since 1994, where experts generally consider that the air safety is very good.

After the crash, Chinese President Xi Jinping called for "the causes of the accident to be determined as soon as possible," and dispatched a government team headed by Vice Premier Liu He to the scene.

The causes of the disaster are not yet known.

All of the people on board were Chinese.

After finding the two black boxes, investigators must obtain within a few days or weeks the first items that will help uncover the causes of the accident.

Hundreds of firefighters, rescuers, doctors, investigators, volunteers and political officials are still flocking to the site of the tragedy to continue the investigation.
