Hijackings are generally associated with the taking of control of an aircraft or other vehicle by force. Some synonyms for hijackings include piracy, commandeering, seizure, kidnapping, and takeover. These words all suggest an aggressive act of taking possession of something that is not rightfully yours. Piracy is often associated with the taking of a ship, while commandeering and takeover may be used to describe taking over a company or organization. Seizure and kidnapping are more general terms but can also be used to describe a hijacking situation. Regardless of the word used, hijackings are illegal and dangerous situations that put lives at risk.
