Jemiba said:From Aviation Week 1977 1-9 a Boeing derivative of the 727, still 3 engined, but
with the tail side mounted engines moved to pods under the wings. Any explanation
why ? Lower noise level in the cabin, for a better acoustic environment ? ???
I can think of three possibilities:
* There are new engines. Perhaps the rear structure would require too much beefing up to support all three of them.
* Space needed for a MAD sting. Support structure and systems for two side engines could make this difficult.
* Perhaps Boeing was also hoping for a follow-on tanker order. Moving those two engines to the wing frees the rear underside for a refuelling boom.
