Sorry but, I'm just not buying the argument that the problems with the hook design is entirely down to wonky data supplied by the USN... I'll use very rough and ready analogy, If I want a builder to build me an extension on my house, and I supply him with the 'data' he needs in order to build it, the very least I'd expect, is for him to check my figures/measurements to make sure they are correct! The USN provide the specs, LM provide the design solution (apparently). If the specs are wrong, fair enough, but surely any significant error in the data should be found long before it gets to this stage of development?
As always, I'm more than happy to be proved wrong, after all, everyday is a school day!
