As for the original pictured -- sure, it's not stable. An aircraft doesn't have to be stable to fly.

You right about the stability question, however there has to be some resemblance of a logically thought out airframe. The F-18 is dynamically unstable… but if you moved the center of gravity forward you could probably fly the thing without stability augmentation. This thing we are looking at has violated every know aerodynamic law that makes any aircraft fly to begin with. The only way to make that thing stable would be to launch it like a bullet (Mach 2 +) and keep it at that velocity, but that inlet speaks of “ducted fan” technology which is not transonic etc.
