cargo door

A cargo door is a large door on the exterior of an aircraft, ship, or truck that opens to allow the loading and unloading of cargo. In aviation, cargo doors are essential for transporting goods and can often be found on freighter planes and some passenger aircraft that also carry freight. These doors are designed to be secure and weatherproof, ensuring that the cargo remains safe during transit. They can vary in size and mechanism, some swinging open while others may slide or fold. Proper operation of cargo doors is crucial for efficient and safe logistics.
