Ugly, the information you have is incorrect- at least according to the information I have!
From my sources within the airline (and not just flight ops) aircraft was repaired for a lot less than $100 Mill. Try finding a replacement 744 at that price!
Further, no matter what, the QF1 in BKK was an 'accident'. The then CEO may have called it an incident but according to the law, it was an accident and treated as such by all QF crew. What you may have heard is that the aircraft was repaired to stop a 'hull loss' appearing on the QF record. See my first paragraph for an answer to that!
Hope the info is uesful!
