RE: BA`s Trent engines

As for your question on engines durability, I dont really think that matters, all engines have to be durable, BA obviously had its reasons as to why it chose Trents for the second batch of 777s, as for the first batch, the Ge 90 was selected for 2 reasons, firstly the trent was not ready, secondly BA were offered a discount for the 777s if it chose the GE 90.

I prefer to use an airline and or airliner that uses RR power as I beleive them to be more reliable, certainly the RB211 535E4 which powers the 757 has the lowest removal and in flight shut down rate of any engine, I also like the rear exhaust cowling on all RR engines with the huge hole, unlike PW and GE, the IAE V2000 and 2500 which pwers some A320/321s are a nice clean engine aswell.
Here is a thought, imagine how many Rolls Royce Dart engines have been produced, and applied to so many types, viscount.herald,748,f27,andover,argosy,namcys 11, fh227, not many reports of engine problems on these ???
