CFM-56 engines on DC-8s allow them to meet current noise requirements and are also very efficient. As far as I know, hush-kits for the 707 are marginal on noise and the old engines so equipped are very fuel-inefficient. I believe USAF re-engined some 707s (AWACS?), but too expensive for commercial use. Rgds, bizfixer@aol.com
