You would have to complete the picture. A-380 stalled out in development. 747-400 freighter line maxed out and conversions couldnt keep up. 777 freighter wasn't available. FedEx combined their MD-10 program and UPS and Fedex and everyone else made all the MD-11s haul through the last growth cycle. 777 makes lots of sense, surprised there are not more A-330 freighters. The 767-300s are still being built.
