> Is there something special about the US’s landmass that UFOs only crash there? Or do superior alien life forms who have the capability to travel between planets and probably solar systems, for some reason are only interested in the U.S. when they come to explore the earth?

Actually, it appears they like nuclear weapons and the associated infrastructure to make them. All of the US atomic weapons plants got a lot of UFO sightings when they were first built and operated, with very little after that. https://www.explorescu.org/post/uap-pattern-recognition-stud...
