True - but we are talking a 50-year difference in understanding of nacelle-fuselage interference and a host of other little aerodynamic details, which may have changed in relative importance to designers over 5 decades.
All the little problems the Vickers guys were trying to address in '61 may be different from the mix Cessna is trying to juggle today.
And the -10 had 4 engines, so a loss of one produced a smaller assymetric thrust problem.
