Cargo planes are specially designed aircraft used to transport goods and materials instead of passengers. They come in various sizes and can carry everything from small packages to large freight containers. These planes play a crucial role in global trade, allowing businesses to ship products quickly across long distances. Unlike regular passenger planes, cargo planes often have large doors and a spacious interior to accommodate bulky items. Some cargo planes, like the Boeing 747 Freighter, are modified versions of commercial airliners, while others, like the Lockheed Martin C-130, are built specifically for transporting cargo. This versatility makes them essential for logistics and supply chains worldwide.
