They Are Exempted From Certain Security Measures
Despite the stringent security precautions that airlines and planes employ, some objects are shockingly allowed on board, notably in the cockpit. For example, most Americans permitted aircraft to store axes.
Axes, while potentially lethal, have their uses in an emergency. They can help get through jammed doors or release someone trapped beneath a seat after an event. As long as the captain’s accountable for the weapon and its usage is confined to emergencies, it may be valuable safety equipment.
