Hi Engines,
Thank you very much indeed for that comprehensive answer. My remarks responding to the comments of John Farley were very much tongue in cheek.
A very complex situation and as you rightly say a flight deck is not a static hunk of concrete. The UK ships are also smaller than there US counterparts which in turn means they may well be more prone to uppy, downy movements
I still have my fingers crossed that all these issues will be resolved but will I get arthritis in my joints before these aircraft become operational?
