Dr. Pais is a decades long researcher for the US Navy. He is credible, but the 'UFO patents' are a thing of lore more than scientific fact. I am seeing the signs of this LK99 patent as something positive, since it was filed in January and has taken a long time to write up and prepare. After at least six months you believe the researchers in South Korea would have ample time to check their own findings before throwing their reputation and time on this.
