In reply to Arnold's question about previous uncontained engine failures during the time QF had it's own engine shops. I was with QF engineering (Line Maint) from 1966 to 2006 and I can't recall an uncontained engine failure occurring on a QF a/c during that time. Yes, there were plenty of turbine & compressor (not fan) blades coming adrift but to my recollection they managed to follow the gas path.
Such failures were apparently not rare during the Connie days and I have seen a couple of other operators JT9D's let go in dramatic fashion.
Hopefully, if my memory is incorrect someone will point my error out.
With regard to the 90 years of Qantas celebration, that is apparently only for current employees according to the Friday Flyer, as a retiree I was certainly not invited.
