Major General William Neil McCasland, a 68-year-old retired Air Force general with reported ties to classified programs and discussions within the Unidentified Flying Object (UFO) community, has been missing since February 27, 2026. His disappearance from his Albuquerque, New Mexico, home has triggered an extensive search and fueled widespread speculation, particularly given its perceived connection to another recent vanishing of an aerospace engineer.
McCasland was last observed leaving his residence for a hike, equipped only with a backpack, wallet, and a .38-caliber revolver. Authorities noted that his phone, glasses, and smartwatch were left behind, which investigators described as uncharacteristic of his usual habits. Despite a comprehensive search operation involving drones, helicopters, K-9 units, and ground crews, no trace of the retired general has been found. Search efforts included door-to-door inquiries across approximately 700 homes in the vicinity. Weeks into the investigation, the only item discovered was a sweatshirt located about a mile from his home; however, its link to McCasland remains unconfirmed, and there were no immediate signs of foul play.
The case has drawn increased attention due to its eerie resemblance to the disappearance of Monica Reza, a 60-year-old aerospace engineer, in June 2025. Reza, who worked on rocket technology connected to programs McCasland once oversaw, vanished while hiking in California. She was reportedly walking just 30 feet behind a companion one moment and was gone the next, with her body never recovered. Both individuals shared deep connections to advanced aerospace research. Reza was employed by Aerojet Rocketdyne, where she contributed to the development of high-performance materials for rocket engines, including technology aimed at replacing Russian RD-180 engines. McCasland, during his distinguished Air Force career, supervised programs related to similar research and previously led operations at Wright-Patterson Air Force Base, a site frequently associated with highly sensitive national projects.
The confluence of these two disappearances, particularly McCasland’s reported involvement in post-retirement UFO discussions, has ignited considerable online speculation. Some sources have characterized him as a "gatekeeper" within the UFO community. Furthermore, the timing of his vanishing, occurring just days after President Donald Trump publicly pledged to release classified UFO files, as reported by the Daily Mail, has further intensified these theories.
However, law enforcement officials are actively working to temper the proliferation of unverified claims. Sheriff John Allen stated that investigators are meticulously reviewing every tip received but cautioned that many involve "outlandish" conspiracy claims, which can inadvertently divert resources and slow down the ongoing search efforts. Authorities have consistently maintained that they have found no credible evidence of abduction, foul play, or any direct link to classified programs in McCasland's disappearance.
McCasland's wife also directly addressed the speculative theories surrounding her husband's disappearance. She acknowledged the existence of these theories but firmly dismissed them, asserting that his limited involvement in UFO circles does not provide a rational explanation for his vanishing. She emphasized that beyond the fact of his being missing, there has been no evidence to suggest anything unusual or conspiratorial.
Investigators did note that McCasland had reportedly experienced periods of "mental fog" in the months preceding his disappearance. Despite this, they underscored that there was no indication he was disoriented at the specific time he went missing. While some former officials have raised the possibility of suicide, authorities have not confirmed any definitive conclusion regarding the cause or circumstances of his vanishing. The pattern of two highly intelligent individuals, both linked to advanced aerospace work, disappearing during routine hikes without leaving clear evidence, continues to be a central point of concern for investigators and the public alike.
