Documented sightings reported in 2026.
After retired AFRL commander Maj. Gen. William Neil McCasland went missing in February 2026, a months-long social-media narrative tracking deaths and disappearances of ~15 U.S. scientists and adjacent personnel - all loosely connected to classified aerospace, advanced physics, or national-security-adjacent work - escalated into a White-House-level FBI investigation. Individual cases have documented mundane causes; the cluster pattern is unusual enough that the federal probe is underway.
President Trump directed the Pentagon and federal agencies to begin identifying and releasing government files related to UFOs, aliens, and UAP.
