First of all, you need to use some punctuation. I'm not trying to be picky, but that is one long-ass sentence.
Second, we can't even built a reliable flying car yet. I don't think we have anywhere near the technology to make a transforming robotic fighter plane. The costs would be insane, and there is no real incentive for anyone to make one.
What would you actually need a plane that can transform into a robot for? Other than it would be extremely sweet to park in the office parking lot, crush cars, pick up babes.... well, I guess there are a few uses for one, but none of them so practical.
