ULD / OLD DIRTY / KG /
2009
A ULD (Unit Load Device) is a container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows a large quantity of cargo to be bundled into a single unit. ULD containers, also known as cans and pods, are closed containers made of aluminum or combination of aluminum (frame) and Lexan (walls).

"Almost all the objects that you can see have at some point been inside a shipping container. In fact, today, 90% of cargo travels by container."
