Your right,
they did re-engine and put a semi glass cockpit in the 727-100's. They put RR tay's on 1 and 3, and zeroed the airframe.The airplane is very powerful, but the Tay's are a real pain. Even with that though they still have 1 JT-8 and 2 tays burning fuel when maybe 2 CFM-56's could do the same job. I was just curious if there were any crew or people in the know. Fedex usually puts in huge orders, I would love to see them fly the 737-900 freighter version.
