As good as it was/is didn't an EAL L1011 come very close to a hull loss when the 'fail safe' shaft failed?
Due in part to a location bearing failure caused by an oil fire inside the LP shaft.
IIRC the fan and shaft assy crawled its way up the 'S' duct and caused the loss of 3 hydraulic systems. I guess in that case the damage was upstream of the hydraulic fuses?
Not long after that a (Fan Catcher) mod. came out. Still it is one damn clever bit of kit...dunno why the RAF make such a meal of it.
