The black box of the crashed passenger plane of China Eastern Airlines has not been found, and the scene is located in the foothills. Does the terrain have an adverse effect on the rescue?

On March 2 1, a Boeing 737 passenger plane of China Eastern Airlines crashed in tengxian, Wuzhou City, Guangxi, while performing a shipping mission from Kunming to Guangzhou. The crash of China Eastern Airlines touched the hearts of people all over the country. Everyone is deeply saddened, praying for a miracle and looking for survivors. After the accident, rescue officers and soldiers such as Wuzhou Fire Rescue Detachment immediately launched rescue operations. At present, the search and rescue operation is still in progress, and some aircraft wreckage has been found. However, the scene is located in a mountainous area, which is not conducive to search and rescue operations. The adverse effects mainly include the following points:

First, the scene of the accident is surrounded by mountains on three sides and the roads are not smooth.

According to reports, the specific address of the plane crash occurred near Shentang Table, Mogao Village, Langnan Town, tengxian, Wuzhou City, Guangxi Zhuang Autonomous Region. This is a remote mountain village in tengxian, Wuzhou. Surrounded by mountains on three sides, we need to go into the mountains for search and rescue. There is only a spacious path into the ravine, and large cars can't get in at all, which leads to the inability to transport heavy machinery such as large search and rescue equipment and power generation equipment. Basically, we can only rely on small facilities such as manpower and drones. First, artificial energy is limited after all, so it is quite energy-consuming to find it in the mountains and plains; Second, the black box is generally only as big as three bricks, which is very small compared with the whole mountain forest, just like looking for a needle in a haystack; Third, there was no electricity at the scene of the incident, and the light in the mountains was not good, which increased the difficulty of search and rescue.

Second, there may be cooling rain, which will affect the search and rescue process.

According to the report of Meteorological Bureau of Guangxi Zhuang Autonomous Region, it is expected that there may be cooling and rainy weather tonight and in the next two days. According to the meteorological station, there was a rainstorm on March 23rd, and the temperature was 12 ~ 18℃. There was moderate rain on March 24th, and the temperature ranged from 15℃ to 19℃. Rain gear and heat insulation products are needed to cool down and rescue rainwater, which adds new challenges to search and rescue operations.

Anyway, no bad news is good news. We all hope that a miracle can happen, and all the accident results have to wait for the official announcement.
