Which of the following groups is historically known to be associated with hijacking incidents?

The group historically associated with hijacking incidents is criminals. This is because hijacking often involves individuals or organized groups with criminal intent, seeking to further their own agendas through acts of violence or coercion. Typically, these criminals might have motivations such as ransom, political demands, or terrorism, which lead them to target commercial aircraft.

The term "criminal" encompasses a wide range of offenders who may engage in unlawful activities, making it the most relevant choice when discussing the historical context of hijacking. Criminals have used hijacking as a tactic to make a statement, initiate negotiations for the release of prisoners, or instill fear among the public and government authorities.

While tourists, journalists, and flight attendants may find themselves in dangerous situations during hijacking incidents, they are not the groups responsible for initiating such acts. Tourists are generally innocent bystanders, journalists often cover incidents from a detached viewpoint, and flight attendants are trained professionals focused on safety and passenger care during emergencies. Hence, these groups do not typically fulfill the role associated with perpetrating hijackings.
