I saw it few times already, and I still thinks the same.
As UAV is part of my day-day life, I just don't see myself, using this aircraft in any operation.
It is no secret that the IDF for example is operating UCAV's, and I'm even allowed to confirm you that, and nothing we use is similiar to that, because of a simple reason.
They decided to go on a structure that fit for human to sit in, and they just closed their minds for new options, which in Israel atlist prooved to work much better.
Such body of an aircraft limits you with the amount of weapon, time in the air, and the goals this aircraft will be able to do in a single flight.
Such aircraft wont give you the benefits you get from the fact that there is no one inside, besides of course, human lives.
Naturally, I'm not allowed to say how those looks in Israel and in the US. and no i'm not talking about the dear Predator :] , but on new designes and technologies that gives the UCAV abillities that a manned aircraft just can't have.
As part of my job, myself and many others UAV's operator, working with people on developing new things, and we donate from our experience of actually flying those things, so they will know what are the problems, and what to focus on, and without beeing arrogant, I just don't think they done it on this specific model.
And don't get me wrong, we work in Israel with EADS and we have joint projects with them ( not as many as with Boeing and Lockheed Marting but we have ), and I know there're great minds and ideas in there, but I don't think this one will work.
