Does anyone have reliable statistics (facts) about the number of engine failures and other major failures (such as holes in fuselage and uncontrolled stuka dives) that Qantas has suffered in the past 10 years, and by comparison the ten years previous to that ie over past 10 years and past 10-20years?
Yes.
Mainly becuase they were Friday aircraft, in that they were manufactured on a Friday on the Boeing assembly line.
Tuesday thru Thursday aircraft are much more reliable.
