Airplane security refers to the measures taken to ensure the safety of passengers and crew during flights. This includes screening passengers and their luggage for prohibited items, such as weapons and explosives, at airport checkpoints. Security personnel, often from organizations like the Transportation Security Administration (TSA), play a crucial role in these processes. In addition to screening, airplane security involves monitoring the aircraft itself. This includes using advanced technology, such as metal detectors and X-ray machines, to detect threats. Flight crews are also trained to handle emergencies and maintain safety protocols, ensuring a secure travel experience for everyone on board.
