Right, absolutely fair comment. I would also add however that people don't realize how much of our understanding of physics needs to be broken for these objects to have a terrestrial technological origin. Consider the following aspects of the observed phenomena: - Intelligent characteristics (chasing / following / loitering behaviour) - Ability to generate and withstand extreme G-forces - Ability to expend/sustain extreme bursts of energy - Lack of visible exhaust - Bizarre aerodynamic characteristics I'm not an aerospace engineer, but I am a technologist and I took some aerospace-related courses in university. The first two aspects combined seem to rule out control by a human in the cockpit, and given the history of AI I would say autonomous control by a computer as well. Although not altogether the possibility of remote control by a human. But the last three aspects transcend not only everything I think I know about existing technology, but also my understanding of: - Newton's Third Law of motion and the rocket equation - Fluid mechanics/Navier-Stokes equation - Thermodynamics i.e., it exceeds our current science by such an enormous margin that I couldn't even begin to approach how to analyze it. Therefore, I think that if we rule out the possibility of a delusion/hoax, it's far more likely that these objects are alien than a secret skunk works project.
