Skyjacking refers specifically to the forceful seizure of an aircraft, including its passengers and cargo. This definition captures the essence of what makes skyjacking a distinct act of terrorism: the unlawful take-over of a vehicle designed for air travel, often involving coercion and the potential for significant harm. By focusing on the aircraft itself, it highlights the unique risks and implications that such an act poses not only to those on board but also to the broader public, as aerial vehicles are heavily regulated and their hijacking can lead to widespread panic and severe security repercussions.

The other responses, while related to various types of unlawful acts, do not precisely define skyjacking and instead refer to different types of crime or attack. For example, the unlawful seizure and detainment of a person pertains more to kidnapping, and a surprise attack by armed forces describes tactics more common in military engagements rather than aviation-related incidents. The statement about the commonality of terrorist attacks due to low risk does not specifically address the act of skyjacking either, focusing instead on broader trends in terrorism rather than the particular nature of seizing an aircraft.
