Powerplant

Suggest you check statement "power to the turbines" The DC9 had radial engines i believe. —Preceding unsigned comment added by Arydberg ( talkcontribs) 19:12, 11 June 2009 (UTC) reply

Please read the article McDonell Douglas DC-9. The DC-9 had turbofan engines, specifically a two Pratt & Withney JT8D mounted in the rear of the fuselage. —Preceding unsigned comment added by El xeneixe12 ( talkcontribs) 06:29, 11 July 2009 (UTC) reply
