At present, the search and rescue and black box search at the scene of the crash of China Eastern Airlines flight MU5735 are in progress.
UAV aerial photography 3D modeling to assist rescue decision-making
CCTV reporter Song Feijing: I am at the core of the China Eastern Airlines crash. Although it is noon, it has been raining in Teng County since last night. The lower the bigger.
The continuous rainfall caused the environment on the site to be very muddy. The soil we are stepping on now is very wet and muddy, and the conditions for this rescue are very bad.
Affected by the rainfall, the search and rescue at the scene, including the black box search, was once suspended this morning, but we saw the leaders, rescuers and experts on the scene urgently consulted on the scene and carefully studied Next step in our rescue program in rainy conditions.
Satellite imagery shows the comparison before and after the accident scene
CCTV reporter Song Feijing: On the one hand, the large-scale search is now suspended, but the work of technical support is still in full swing to provide guarantee for the next rescue.
There is a screen in front of me. Through the continuous efforts of the rescue technicians in the past two days, the 3D modeling map of this drone aerial photography has been completed.
On the left side of this picture, we can see that there is another picture, which is a satellite bird's-eye view before the accident that was urgently retrieved by the rescuers.
By comparing these two pictures, we can clearly see a change in the accident scene before and after the accident.
Let's start with the picture on the left. Following this trail is the way our rescuers entered the core site on foot.
Before the accident, the entire site was an area covered with dense vegetation. The two hillsides were interspersed with this col, and the vegetation was relatively dense.
Then we look at the picture on the right, and now the vegetation in this part of the col has been destroyed.
On the north side of this col, we saw a charred area, which should be the area where the wildfire burned after the accident at that time.
CCTV reporter Song Feijing: At present, there is such an area where the land is exposed, and there is also a scorched environment on the scene.
This part is the core area of the accident where we have connected many times before. There are some white mottled spots on the scene, which should be the wreckage of the passenger plane scattered after the crash on the scene.
So this picture is not just a plane, but also a three-dimensional picture.
The whole picture can be seen from the bird's eye view to understand the situation on the entire surface, and can also observe the entire 360-degree rescue scene in detail through another horizontal angle.
In the past two days, rescuers have been walking to the scene through such a small road.
Although the area of the entire site is not large from the picture, in fact, according to the rescuers, the entire fire area, including the area we are searching for, should be an area of more than 20,000 square meters according to preliminary estimates.
And this square meter is just an area of a plane, which is actually a large site with a height difference.
Therefore, whether the rescuers are carrying out the search and rescue of personnel or the search of black boxes, they have to carry out a great difficulty in this difficult situation.
