So we're trying to encourage the equipment suppliers now to look again at what they have won on business for Eurofighter and perhaps allocate the work between themselves a lot more efficiently so that instead of each one of the four members building a given percentage of the five items, they say right we'll take this one, all of it and we'll build all of it, you take that one, all of it and build that one and so on an and in that way we might be able to er  er improve considerably on the  costs of production.
