The established distribution system is in the process of being restructured to combat the effects of high cost energy, inflation and environmental restrictions. As a part of this system, the air freight industry, also, must re-examine its options in equipment, energy reduction, financial risk and services offered. In the area of investment and energy reduction a cost effective solution is already available. That is, equip a portion of the existing cargo fleet with new technology, quiet, fuel efficient engines. Ten airlines have stepped up to this solution and are re-engining their fleets of DC8 aircraft with CFM56 engine.
