install high-ratio bypass engines deep within the wing structure, with very long inlet and exhaust ducts
BEags, to be fair though the MR1, R1 and MR2 had something similar and I can't remember there ever being an uncontained blade failure. OK so it was the Spey engine and that would pretty much eat anything thrown into it with a small cough; are you saying the BMW/RR engines on the 4 were more susceptible to throwing blades?
