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.
