Yawn. At this point, I think the gov't keeps the UFO stuff going because it provides a convenient cover for their own black site technologies. Who would protest a nuclear-capable stealth fighter when they think it's the little greys paying our planet a visit?
Using air-powered vehicles for wars has only been a thing for about 100 years, and in that time we've made astounding leaps forward in mobility and speed. A VTOL from the 80s would seem like a UFO to a Spitfire pilot from the 40s. We also know that modern governments obscure their military technological developments and try to spread disinformation.
Drones can easily replicate a UFO appearance above a given city.
The government was denying everything until a few years. We're talking almost 70 years of blaming everything on swamp gas, blimps etc then suddenly its "possible we're not alone."
Then we had NASA spend millions of dollars on a study recently on how the world would react if they announced the existence of another civilization outside earth. This was back before the funding grant too.
And I dont agree with the spitfire vs VTOL comparo. The WW2 pilot would be able to ID signs of how it operated. The exhaust plume for example would indicate thrust and engine location. The aero cabin shape and wings and vertical stabilizer would make perfect sense too.
These craft literally don't make any sense, no exhaust, no IR heat from any engines and can operate at speeds that should shatter known alloys. Also, no sonic booms and underwater transversal at incredible speeds.
It's like that pilot said, not only is the tech a massive jump but the understanding of physics.
Then also you couple that we sightings of strange metallic objects before the 1920s in the sky with similar descriptions. They could all be lies/confusion I suppose but there were some credible sources.
My personal opinion is starting to shift after talking to my father. I just find it odd that his account on a submarine mirrored that of these operators, but 25 years prior.
