As I recall, the original 757 program was a 727 re-engined with 2 big engines on a new wing, with new avionics and such. As the project progressed, it diverged from the 727 airframe. Boeing designed a new tail that reduced weight, drag, and overall length of the plane, and a new nose that reduced drag and cockpit noise while increasing space and commonizing with the 767 cockpit. I think each of these modifications also added a couple rows of seats. American once proposed re-engining existing 727's with newer engines on the old pylons, with the center hole plugged. This would, of course, cost a whole lot less than buying a bunch of shiny new airplanes. Boeing managed to convince them that it wouldn't be worth the trouble, as they wouldn't have the new wing or new flight management systems. Not only would this make them less economical than a 757, but would probably still require a flight crew of 3. <snip> -- -Stephen H.
