There are specific procedures and trained personnel to handle the scenario. It would not be wrong. Airline attendants and pilots have been taught to control the violent passengers. The situation is still very scary. This video shows an extremely frightening moment when a man tries to get past the flight attendants. It is probable that the man will require bail bonds for emergencies if he is let out without bail.
In the event that violence is imminent, the personnel must think fast. In this clip, you see how some quick thinking proved to be successful. It was a challenge for the man with a violent streak to control. It was fortunate that they had spare duct tape to hand. The flight attendants efficiently used the duct tape to secure up the man. He was then taped to his chair. It worked until the plane landed and the police took control. It is possible for people who were injured to be hurt if the flight attendants did not act promptly enough.
