The disappearance of retired U.S. Air Force Major General William Neil McCasland has captured national attention, blending elements of military service, advanced research, and longstanding associations with UFO-related speculation.
McCasland, aged 68, was last seen on February 27, 2026, around 11 a.m., when he left his home on Quail Run Court NE in Albuquerque, New Mexico, on foot. He has not been in contact with family or friends since, and authorities report that he left his cell phone behind at the residence. The Bernalillo County Sheriff’s Office (BCSO) issued a Silver Alert the following day, highlighting concerns for his safety due to an unspecified medical issue.
Described as an avid outdoorsman, McCasland was known to frequently hike, run, and cycle in the Northeast Heights and Sandia foothills areas near his home. Search efforts have focused on these rugged terrains, including activations of New Mexico Search and Rescue teams in locations like the Elena Gallegos Open Space, where some clothing items were discovered (though not confirmed to belong to him). Investigators have canvassed neighborhoods, interviewed residents, and requested home security footage from over 600 nearby homeowners to gather potential leads.
Due to McCasland’s distinguished military background, the search has involved multiple agencies beyond local law enforcement. The FBI’s Albuquerque Field Office and personnel from Kirtland Air Force Base are actively assisting, coordinating resources and expertise. The BCSO has emphasized these partnerships in public updates, noting the case’s complexity.
McCasland’s career in the U.S. Air Force spanned decades and included high-level roles in science, technology, and research. He served as commander of the Air Force Research Laboratory (AFRL) and the Phillips Research Site at Kirtland Air Force Base in Albuquerque—installations tied to advanced aerospace and weapons development. Earlier in his career, he commanded elements at Wright-Patterson Air Force Base (WPAFB) in Ohio, a facility long steeped in UFO lore and conspiracy theories. WPAFB has been rumored in popular culture to house extraterrestrial materials or technology (such as alleged debris from the 1947 Roswell incident), though no official evidence supports these claims.
His expertise extended into classified programs involving space systems and aeronautical engineering. An alumnus of the U.S. Air Force Academy with advanced degrees from MIT and Harvard’s Kennedy School of Government, McCasland retired around 2013. More recently, reports indicate he had limited associations with the civilian UFO/UAP (Unidentified Anomalous Phenomena) community, including brief consultations related to public figures interested in the topic—though his wife has described any such involvement as minor and not central to his life.
The case has sparked widespread speculation online and in media, with some outlets and commentators suggesting links to his past roles or purported knowledge of sensitive subjects. Investigative journalist Ross Coulthart has publicly called the disappearance a “grave national security crisis” due to McCasland’s institutional knowledge of advanced programs. Others have made lighthearted or conspiratorial remarks, but authorities have not indicated any foul play or extraterrestrial involvement, treating it primarily as a missing persons case with medical urgency.
As of mid-March 2026, nearly two weeks after his last sighting, no confirmed sightings or breakthroughs have been reported. The BCSO continues to urge the public to come forward with any information, no matter how small. Anyone with tips is encouraged to contact the Bernalillo County Sheriff’s Office directly.
The search remains active, with hopes that McCasland—known for his love of the outdoors—will be located safely soon.
