I don’t understand the confusion.

it was Unidentified, Flying, and It was it was Likely Ours

just because something is Unidentified does not make it Alien or Extraterrestrial, The odds of that are really vanishingly small.

You're the one bringing alien/extraterrestrial into the conversation.

If these aircraft belong to our enemies, this is a game-changer.

You would likely enjoy the well-written book by Renato Vesco titled “Intercept UFO” or “Intercept but Don’t Shoot”.

It outlines the suction-based boundary layer control technology that the Allies scored at the end of WWII and started appearing only 2 years later.
