Over the past year there has been a lot of duff information/rumour spread about the C-17 , but the fact is (imho) that this has been the most succesful introduction of a new aircraft type into the RAF for many years, if not ever.
Does anybody DIRECTLY conected with the C-17, be they aircrew, movers, techies or indeed end-users have any negative comments about it, other than why didn't we buy/ get more, etc?
