Economics/costs of acquiring & converting 737-200s & -300s/-400s to freighter, Issue 17 Jun/Jul 2001
The 737 is searching for a secondary market, and can provide the same
payload capacity as the 727-100F. Conversion of the 737-400 depends on
market values being low enough. Has the 737 yet reached, or is about to
reach, the stage where conversion is economically viable?
