Situations requiring prompt delivery of goods occur quite often. The use of cargo aircraft is necessary not only to increase the speed of air communications. Delivery by air may also be needed in the case of inaccessibility of the addressee, the presence of perishable goods, transportation of especially valuable and unique items or papers.
In the recent past, international air cargo transportation was considered an exotic and expensive pleasure. The situation has now changed radically. The progress of aviation technologies, the growth of airport infrastructure, the optimization of international logistics links, the emergence of healthy competition between carriers and the reduction in prices have made air transportation of goods as affordable as possible for the consumer.
