Jinda,
I am sure they will.............I will watch to see who is smiling. It is valid that the original comment about 3:1 posted by someone else was crude, but if we are talking about the manpower, engineering effort, cost (including future engine upgrades) and associated support to achieve Fe@R, then we indeed do have a valid debate, which it is very easy to 'cuff-off' without supplying any facts. It is a sad fact that much of the chat on these forums, is ill informed and consists of 'you are talking @@@@@@' rather than supplying evidence. Unfortunately much of the evidence could of course, not be provided on such a public forum but, there are some on Pprune, who quite clearly have access to such evidence and it is relatively easy to identify who they are as opposed to the enthusiast or the retired Officer who is being fed single service Dogma and propoganda, without the benefit of an opposing view.
Of course, as always, no offence intended
