FBI internal memos from 1950 document OSI concern over green fireballs and discs appearing near sensitive installations in New Mexico. Dr. Lincoln La Paz of the University of New Mexico concluded that roughly half the recorded phenomena were meteoric; the remainder he attributed to possible U.S. guided missiles or, if that interpretation was wrong, to guided missiles launched from the Ural region of the USSR.

In late 2025, a senior U.S. intelligence officer and two pilots departed a Joint Operations Center by helicopter to investigate loud thuds and UAP sightings over a weapons test range. Hovering at 700 feet AGL, they observed countless orange orbs swarming near a mountain, then two large oval orbs stationary just above the rotor disk that expanded into a "T" formation of four or five before dimming over 10 to 15 seconds. Orange orbs also appeared directly above transiting fighter jets, matching their speed and flight path, and separately formed a triangle formation before vanishing.

Orange orbs, oval-shaped with white or yellow center, emitting light in all directions, observed stationary just above rotor disk to the right of helicopter at approximately 700 feet AGL

On September 1, 2015, at approximately 0710 hours, the Pantex Plant Ground Surveillance Radar detected an unknown object flying west of the facility near Amarillo, Texas, traveling north at 10 to 15 mph. Protective Force personnel followed the object by vehicle for several miles; a lieutenant and SPO observed it through binoculars and described it as a "diamond" type shape, approximately 4 ft. tall and 2 ft. wide at the bottom, with no audible sound and no identifiable propulsion system. The object was last seen heading ENE near County Road G and F.M. 1342 in Carson County before personnel lost sight of it.
