Cargo aircraft are specialized airplanes designed to transport goods and materials rather than passengers. They come in various sizes and configurations, ranging from small planes that carry local shipments to large freighters like the Boeing 747 that can move heavy and oversized cargo across long distances. These aircraft often have large doors and a spacious interior to accommodate different types of freight. Many cargo aircraft are equipped with advanced technology to ensure safe and efficient loading and unloading. They can carry a wide range of items, including perishable goods, automobiles, and industrial equipment. Cargo airlines, such as FedEx and UPS, rely on these aircraft to meet global shipping demands.
