Count Von Altibar,
We are not one of the first delivery customers for the 787, therefore it seems that the current delays will not affect VS too badly.
That word came from our Aircraft Integration Manager a few days ago. However, that missive came before the further delays announced earlier this week.
On the Command front, it all depends on whether the 787's are for expansion, or replacements of existing airframes.
Timings wise, I would expect 10 to 12 years (for any new joiners) from now if the airframes are for expansion. 15 or more if the airframes are replacements.
That is only my opinion, but I think it's probably quite accurate.
Perhaps Scroggs can add his experience to the mix on this one?
