In the movie "Captain", Captain Liu Changjian used to be an air force pilot, received professional flight training and drove a bomber. Moreover, he has been on the Sichuan route hundreds of times and has rich driving experience. Therefore, relying on his rich experience and judgment, he finally decided to lower his flying altitude and return to Chengdu at the first time, and issued an emergency code of 7700 to let all the staff and 1 19 passengers land safely.

There is a clip in "Captain" in which a flight attendant is training a line that has never been used before: Please believe that you have received professional training. Have confidence and ability to ensure their own safety.
