Actually, primitive airports were a major consideration for both these planes,
as they were being sold as short and medium range "feeders" to replace places
that were still being served by DC-3s in the early '60s.  The 727 was actually
certified for and used on gravel runways in Alaska; conditions that a
under-slung engine could not survive.
