I watched a video from a fighter pilot yesterday where he was evaluating the pictures and video of this plane, and he stated that he was CERTAIN that there was no way this was a fighter. Too big, not enough material or articulation in the control surfaces, no obvious thrust vectoring, etc. He surmised that it could be a drone mothership, a bomber, or carry a bunch of stand-off missiles, but in a dog fight it would be dead meat.
