Baggage screening is a security process used at airports to inspect luggage before it is loaded onto an aircraft. This procedure helps ensure that dangerous items, such as weapons or explosives, are not brought on board. Screening typically involves the use of X-ray machines and other technologies to examine the contents of bags. Passengers are usually required to place their bags on a conveyor belt for screening. Security personnel may also conduct manual checks if something suspicious is detected. This process is essential for maintaining the safety of all travelers and crew members aboard the aircraft.
