Aircraft piracy is a serious offense that involves hijacking or seizing control of an aircraft in mid-air. To describe this act, there are several synonyms available such as air piracy, skyjacking, aircraft hijacking, and airborne terrorism. These words all convey the same meaning, that is, the act of illegally taking over an aircraft for personal gain. Aircraft piracy has been a major concern for civil aviation since the mid-20th century, leading to the establishment of strict security protocols and regulations in airports and airliners worldwide. The use of these synonyms helps to convey the gravity of the act and allows for clear communication in any situation involving aircraft piracy.
