What is the real point of these 35+ pages of chatter? Not a single one of us really knows the end cost for repairs - or the as-is value of this air frame. The ONLY parties able to make that call are those bidding on doing the repairs (Boeing?) and what contributions RR and BA's insurance carrier will make. In the end, the decision will be made by BA. They will either repair it or offer it in the market (at a "Fire Sale" price) and move on.
See past 672. You could have saved yourself some trouble and at the same time looked something other than clueless regarding the engine mfg.
