Perhaps seventy years ago someone would have said that they wanted to ship goods by plane from one place to another, everyone would be surprised. But it is enough to look around to see that most of the goods we use every day are made abroad and many of them have reached Iran by air. Today, the transfer of goods by air has become normal and thousands of tons of cargo is transported daily from other countries through the air transportation system in Iran. Air transport is a type of transport whose main feature is the transport of goods (or persons) by air. In air transport, all kinds of goods are moved between two points and goods are delivered from the sender and delivered to the recipient. This method uses a wide variety of means of transportation. People think that air transport is done only by plane, but this is a misconception.
