On October 29th, an aviation blogger revealed that China Southern Airlines flight CZ3121 from Guangzhou to Beijing was delayed by 3.5 hours due to a suspected coin thrown at the engine. That night, Southern Airlines confirmed the incident and stated that the crew found two coins in the area near the belly of the plane. After a comprehensive inspection, the plane safely arrived at its destination. The passenger involved has been taken away by the airport police to cooperate with the investigation. Throwing a coin at an aircraft engine is considered a "dangerous action". If a coin is sucked into the core of the engine, it is likely to collide with the high-speed rotating blades of the engine, which can easily cause the engine to stall or even stop running. However, in recent years, incidents of throwing coins at aircraft engines have occurred from time to time. Some people believe that throwing a coin at a plane can "avoid disaster and pray for blessings," but are unaware of the consequences of this behavior. To ensure aviation safety, once a coin is thrown at an aircraft, the airline will take the most cautious attitude to handle it, which inevitably leads to flight delays and cancellations. This not only causes economic losses to airlines, but also brings inconvenience to the normal travel of passengers. The act of tossing coins at an airplane can be described as a dual destruction of public safety and order. Throwing coins into airplanes also faces serious legal consequences. The Law on Public Security Management Punishments stipulates that those who seriously disrupt airport order shall be detained for not less than 5 days but not more than 10 days, and may also be fined not more than 500 yuan. Coin throwers also face civil liability. According to a case released by China Judgment Document Network, Lu, who was traveling with a child, was not only detained for 10 days for throwing two one yuan coins into a plane, but also sentenced to compensating the airline for over 120000 yuan. And the beginning of all this is the superstition of the local rural elderly: the first time a child takes a plane, they throw two coins as "road money". People can't help but ask, in recent years, there have been many media reports on the act of throwing coins into airplanes. Why do similar incidents continue to occur one after another? Undoubtedly, coin throwers lack basic scientific literacy. It is understandable to care about one's own and family's safety when going out, but when 'ensuring safety' is manifested in a superstitious way, it leads to the opposite of safety. They pray for safety, but pose a threat to their own safety, as well as the safety of fellow passengers and crew members. No wonder some netizens suggested jokingly that airlines add "prayer boxes" in their planes and support scanning payment. On the other hand, it should also be noted that coin flippers often lack experience in flying, even for the first time. On September 15th, relevant officials stated at a press conference of the Civil Aviation Administration that preliminary statistics show that only over 300 million people in China have traveled by plane. In other words, there are still over 1 billion people in China who have never taken a plane, and their knowledge of air travel is of course very scarce. At the same time, with the development of the economy and society and the improvement of people's living standards, more and more people are choosing air travel. This means that for a period of time from now to the future, there may still be people in the large group of "first time passengers" who have the idea of "throwing coins into airplanes can pray for blessings". In this regard, the civil aviation department and airlines should not only strengthen management to prevent similar incidents from occurring, but also provide“
