Please don’t confuse this topic with the other request. That one is for the normal “F” Variant but this is for the “CF” Variant
Martinair, legally Martinair Holland N.V., is a Dutch cargo airline headquartered and based at Amsterdam Airport Schiphol and a subsidiary of Air France-KLM. The airline was founded in 1958 by Martin Schröder. Since 2011, Martinair has operated entirely as a cargo airline with scheduled services to 20 destinations worldwide and additional charter flights. Prior to that date, passenger flights were also operated.
Some of Martinair Cargo’s MD-11s are MD-11CFs (Converted freighter). These CF MD-11s were previously served as Passenger airliners and are now converted to freighters. Martinair’s CFs though, have a very nice special feautre. While they are operated for Cargo operations, they have windows! And I think that Martinair’s livery looks better with windows. It just feels nice. And yes, I agree that it also looks a bit confusing. Sadly though, Martinair has now retired both it’s MD-11Fs and MD-11CFs and is only operating Boeing 747-400BCFs.
