Insights

Aviation History

The 747-400F is the dedicated freighter version of the legendary 747-400, one of the most significant widebody cargo aircraft in history and a backbone of global air freight.

Fleet Rarity

747-400F freighters are fewer than 120 active globally, less than 60 in Atlas’s fleet. Becoming rarer as the -400 is retired in favor of 747-8F or 777F.

Record Flights

Operates some of the longest nonstop air cargo routes (e.g. transpacific, transatlantic) but not record-setting in range compared to new-generation types.

Safety & Events

Some 747-400Fs have been involved in non-fatal incidents, including engine issues and cargo-related incidents, but N479MC is not known for major incidents.

Future Outlook

Many 747-400Fs are being phased out this decade as new freighters come online; however, Atlas still operates a significant number.
