Civilian cargo aircraft are specialized airplanes designed to transport goods and freight rather than passengers. They come in various sizes and configurations, ranging from small regional planes to large wide-body jets. These aircraft are essential for global trade, enabling the quick movement of products across long distances. Many civilian cargo aircraft are modified versions of passenger planes, allowing for larger cargo holds and specialized loading systems. Major operators include companies like FedEx and UPS, which utilize these aircraft to deliver packages efficiently. The use of civilian cargo aircraft plays a crucial role in supply chains and logistics worldwide.
