Airport security screening is a process designed to ensure the safety of passengers and aircraft. It typically involves checking luggage and personal items for prohibited items, such as weapons or explosives. Passengers must pass through a metal detector or body scanner, while their bags are scanned using X-ray machines. Security personnel, often part of Transportation Security Administration (TSA) in the United States, monitor the screening process. They may conduct additional checks if something suspicious is detected. This process helps maintain a secure environment for air travel, allowing passengers to board their flights safely.
