This is a long and entertaining thread which I have been reading with great interest.
However, I think it is about time that this crew was complimented for a job well done. The flight was conducted safely, efficiently and professionally.
Part of a professional pilot's job is to operate economically for the company with safety being the overriding consideration and this is precisely how this crew operated.
Having to deal with even a "technical" emergency at the end of a 9/10 hour flight on three engines cannot have been easy and I think the crew should be commended for acting in the correct manner.
In conclusion, I say, WELL DONE!
