Greenknight, I think you'd do well to look at the source of the "passed with flying colours" article. The Navy newspaper is a bit like Pravda - you'll never see any bad news in it and everything is sweetness and light within the Senior Service if everything you read in it is true.
I have been led to believe that the MRH-90 still has quite limiting sea state restrictions. If that information is untrue, I'm sure someone here will be quick to tell me - but please, don't quote 'Navy News' (or whatever) as your source.
