A cargo system is like a big toy box for grown-ups. Just like you have a toy box to keep all your toys organized, the cargo system helps people keep all their important things organized on airplanes or ships.
Let's say we have a big airplane that needs to carry a lot of things from one place to another. These things could be clothes, food, toys, or even cars! In order to make sure everything fits in the plane, we need to organize them really well. This is where the cargo system comes in.
The cargo system is made up of big metal containers (kind of like your toy box) that are specially designed to hold different types of things. We can put all the heavy things in one container and all the light things in another container. This way, we can fit more things into the airplane without running out of space.
Once we have all the containers filled up, we can put them into the airplane using special machines called loaders. These loaders are like giant robot arms that can lift really heavy things and move them around.
Once the airplane takes off, all the containers stay in place so that they don't move around during the flight. This helps keep everything safe and makes sure that nothing gets broken.
When the airplane lands at its destination, the containers are taken out of the airplane and loaded onto trucks so that they can be delivered to their final destination.
So, basically, the cargo system is like a giant toy box that helps people organize and transport things safely from one place to another. Cool, huh?
