Feb 2026 Unexplained Disappearance of Air Force Major General William Neil McCasland
There is significant recent coverage about Retired U.S. Air Force Major General William “Neil” McCasland, born around 1957 or 1958, age 68 at the time of events. He is an astronautical engineer who served in the Air Force from 1979 until his retirement in 2013. 
Military Career Highlights
McCasland graduated from the U.S. Air Force Academy with a Bachelor of Science in astronautical engineering. He later earned a Ph.D. in the same field from MIT under a prestigious fellowship.
His career focused on space research, acquisition, operations, and advanced aerospace technology.
Key roles included:
- Commander of the Air Force Research Laboratory (AFRL) at Wright-Patterson Air Force Base in Ohio (2011–2013), where he oversaw billions in science and technology programs, including advanced materials and future weapons research.
- Earlier command of the Phillips Research Site at Kirtland Air Force Base in New Mexico.
- Positions in the Pentagon, the National Reconnaissance Office, and as Director of Special Programs in the Office of the Under Secretary of Defense for Acquisition, Technology and Logistics. 
Wright-Patterson AFB has long been linked in popular culture and conspiracy theories to UFO investigations (e.g., historical ties to Project Blue Book), which has fueled speculation in recent coverage, though official reports emphasize his work on conventional advanced aerospace research.
His wife has reportedly stated that any involvement in UFO-related matters was limited and did not involve sensitive classified details. 
Recent Disappearance
The main current attention stems from his unexplained disappearance. McCasland was last seen on February 27, 2026. He left his home in Albuquerque, New Mexico, in the Sandia Heights area near Quail Run Court NE on foot around 11 a.m. for what was described as a trail run or hike.
He left behind his cell phone, prescription glasses, and wearable devices. A gun and wallet were reportedly unaccounted for in some accounts. He has not been in contact with family or friends since. 
Search efforts: The Bernalillo County Sheriff’s Office is leading the investigation, with assistance from the FBI Albuquerque Field Office and other agencies.
A Silver Alert was issued. No evidence of foul play has been publicly confirmed, and authorities describe it primarily as a search and rescue effort rather than a criminal case.
He is described as an experienced hiker and outdoorsman.
- Physical description: Approximately 5’11” tall, with white hair and blue eyes. He was last seen wearing a green button-up shirt.
- As of mid-to-late March 2026 reports, with some mentions into early April, he remained missing, and searches including in the nearby Sandia Mountains had not yielded confirmed leads or sightings. 
Additional Context and Speculation
His disappearance has drawn widespread media attention from outlets like CNN, ABC, CBS, USA Today, Fox News, and local New Mexico stations.
It has also sparked online discussion and some conspiracy-oriented speculation due to:
- His command of AFRL at Wright-Patterson, often tied to UFO lore in public discourse.
- Connections to advanced defense/aerospace research.
- A separate disappearance of aerospace engineer Monica Jacinto Reza, who reportedly worked on projects linked to or funded under areas McCasland oversaw, which some commentators (including Rep. Tim Burchett) have noted as part of a broader pattern involving scientists in sensitive fields. 
However, law enforcement and former investigators, e.g., retired FBI agents commenting in media, have cautioned against jumping to extraordinary theories. They were framing it as a missing person case involving an avid outdoorsman who may have encountered an accident or medical issue while hiking.
Official Biography
For his full pre-retirement service record, see the official U.S. Air Force biography page, still available online as of recent crawls.
If you’re looking for updates on the search, his Wikipedia page, under Neil McCasland summarizes the basics, including the disappearance note.
Local news from Albuquerque or Bernalillo County Sheriff’s Office releases would be the best sources for the latest developments, as the case was still active into March 2026.
