Although the field work is drawing to a close, there are still many extended tasks, such as decoding the black box, appeasing the families of the victims and related compensation work. What the whole people are most concerned about is the cause of the accident. We need to wait until the final decoding work is completed, and after scientific research, we can reach the final conclusion.
