Looking at the videos we get to see an interesting IR signature, it reminds me of the Alcubierre drives displacement field:
I see this phenomena as an object being displaced rather than being propelled. There's nothing that resembles any known method of propulsion that could have something of that size go that fast and maneuver so quick without producing a lot of heat.
It looks like the air directly around the object is cooler than the ambient air.
If I were to make a wild guess, I'd first say its some cutting edge electronic warfare. Maybe they have something that can manipulate a large range of the EM spectrum in such a way that creates both an optical illusion and show up as an object on both radar and infrared systems. Think of a laser system that can focus on a single point in space. Maybe its 1 laser, maybe its an array. Just remember, visual light is still made up of wavelengths of the EM spectrum. We have tons of systems that can manipulate radar / ir signatures so its fun to imagine they could eventually manipulate our very eyes.
I'd like to assume your average person can't fully conceptualize cutting edge, top secret military technology.
Second guess would be that were actually seeing some weird stuff happening with missiles or drones doing weird shit during training that they caught on video. The clips are super short, the fidelity is super low and we have our DoD publicly stating they have a weak point in their intelligence as they have no reasonable explanation for any of these. I think someone attached to some alphabet agency in this country knows what's in these videos and I believe they are being released as part of some information op to either gather or distort information. Just because youre a fighter pilot doesnt mean you get to know about everything. Also, Jeremy corbell is a guy attached to releasing some of this "leaked" footage before the pentagon had anything official to say about it. I'm suggesting theres a conspiracy. There has to be a strategic reason we are seeing these videos and the pentagon is acknowledging them.
How these clips were edited and distributed also strikes me as odd.
The answer is always easy if you're asking the right question.
Id like to know what questions we should really be asking.
