Freighters

Antonov 124s do it, Boeing 747s do it, even ATRs do it - they all serve as freighters, aircraft that carry cargo in bulk.

Cargolux, DHL, FedEx and UPS are some of the world's most recognised airlines, but none of them carry paying passengers.

More than 2,000 aircraft are registered in operation as commercially owned freighters, with hundreds more assigned to military air arms.

They deliver stuff all over the planet, much of it essential to daily life. It's a fascinating operation.

Whatever your interest in aviation, this eagerly awaited special provides a detailed insight to the world of cargo aircraft.
