Delay
For the 787 at least and the Trent 1000, there's the test-bed incident which happened before the Qantas problem(s?) - the whole shebang must surely have a bearing on 787 testing, production and deliveries, not to mention any possible effects on A380 production ... I sincerely hope that RR have got a handle on this (these) questions. After all, there were also some questions about a certain fuel/oil heat-exchanger in the recent past, and what must be a "certain cloudiness" in RR's reputation ...
