Why do I have to prove ALL of them?
Most UFO are simply unidentified prosaic phenomenon like weather balloons, Swamp gas , radio controlled drones, meteors, ball lightning, etc.
Requiring ALL sightings to fall under one umbrella 🌂is extremely irrational.
By calling boundary layer control experiments “airplanes without flaps” , you betray your own ignorance of the technology, such as related sinterization processes and how it conquers skin friction drag.
Apply some rational thinking here, as well as some good common horse sense.
So you got nothing. That’s what I thought.
