A cargo plane is a type of aircraft specifically designed to transport goods and materials rather than passengers. These planes come in various sizes and can carry a wide range of cargo, from small packages to large freight containers. They are essential for global trade, allowing businesses to ship products quickly and efficiently across long distances. Cargo planes are equipped with features that facilitate loading and unloading, such as large doors and reinforced floors. Some models, like the Boeing 747 Freighter, are modified versions of passenger planes, while others, like the Lockheed Martin C-130 Hercules, are built solely for cargo transport.
