From New York Post:
The mysterious disappearance of a retired Air Force major general with deep expertise about UFOs who went missing without a trace Feb. 28 constitutes a “grave national security crisis,” according to an investigative journalist.
Local law enforcement said William Neil McCasland, 68, disappeared after leaving his Albuquerque, New Mexico, home on foot, leaving his phone behind in a missing persons investigation that has since been joined by the FBI. “This is a man with some of the most sensitive secrets of the United States in his head,” journalist Ross Coulthart said in the latest edition of his “Reality Check” podcast, adding that McCasland possesses deep knowledge about what the US government might be hiding regarding extraterrestrials.
