Let's put this into perspective. A Fan/Disc failure on the centre engine of a Tri-Jet is a different thing altogether. Cold someone in the know please tell us with authority, just how many accidents (by definition causing injury or death) have occurred on four-engined public transport aircraft following Fan/Disc failure? So as to give a fair comparison, it should differentiate between turbo-jet, high by-pass turbo-jet and the latest turbo fan engines.
This is a genuine question, I simply do not have the facility to research it myself.
