| Aug 15, 2018 at 20:43 | comment | added | Vikki | @PeterKämpf: No, but it does mean that they were solvable - which contradicts your assertion that having tail-mounted engines "rules out those designs... for refitting with more modern engines.". | |

Developing those was a major effort, even for Boeing, so the big engine could be fitted into the restricted space between wing and ground. Note, however, that Boeing has since also added a newly-developed wing to capture the benefit of supercritical airfoils. | |
