As for foreign ownership of sensitive contracts, most of you will have heard of the Typhoon I guess.
Now let me see, I would imagine Captor and Dass on that particular aircraft are well up the manifoil tree. Selex Galileo/Finmeccanica have responsibilty for those and just happen to be an Italian company. In fact they inherited the whole of the expired GEC/Marconi empire. Amazing, but true.
