Chapter 15 Air Heist
Thirty minutes after the plane took off, two men rushed into the aft catering room, pointed a pistol at the stewardess, and asked her to connect to the captain's in-flight phone.One of the criminals snatched the phone from her hand: "Is it the captain? Listen carefully! This plane has been hijacked by us, and the stewardess is a hostage. Please follow my orders. First, let all passengers fasten seat belt."

"Understood, what is your purpose?" The captain replied. "I'll tell you about this later, tell me to fasten your seat belt!" The criminal immediately hung up the phone.Immediately there was a sign to fasten your seat belt on board.There was a lot of noise in the cabin, but everyone started to fasten their seat belts as instructed. "You all, sit in the empty seats and fasten your seat belts!" The criminal ordered the flight attendant, and then grabbed the phone to talk to the captain: "Now I want to go to your place and open the door of the cockpit for me. Don't do anything stupid, my companions here are holding passengers hostage." "Got it. Come on, let's talk."

Two criminals appeared in the cabin with handguns.While walking slowly through the aisle, make sure that all passengers are wearing seat belts.Among them, one person stood in the middle of the aisle and gave a loud speech: "Everyone, we hijacked the plane. We don't intend to hurt you. Release the women and children after arriving at the destination..." But this kind of interesting speech could not be completed. .A few seconds later, the situation changed, and the incident quickly came to an end. The two hijackers were subdued by the passengers without any resistance.Why is that?
[Answer] While the hijacker was giving a speech, the captain manipulated the aircraft to drop about 50 meters suddenly, and then rose about 30 meters, causing the "air trap" phenomenon.As the two hijackers were standing in the aisle without seat belts, they hit their heads hard on the cabin roof and fell down in shock.Passengers and flight attendants were all wearing seat belts, so they were safe.Aerial trap, also known as "turbulent air flow", refers to the phenomenon that the aircraft suddenly falls due to the drop of air flow in the air.
