Gorman Dogfight — USAF F-51 Pilot, Fargo

◎Fargo, North Dakota, USA

USAF Lieutenant George Gorman pursued a fast-moving luminous orb for 27 minutes over Fargo in his F-51 Mustang. The object executed head-on passes, outran the F-51, and climbed vertically faster than the aircraft could follow. Independently confirmed by control tower operators and two CAA controllers. Project Sign investigated and listed it as one of the 'best unexplained' cases.

Sandia — Armed Forces Special Weapons Program Orb Encounters

◎Sandia Base, Albuquerque, New Mexico, USA

Newly declassified Armed Forces Special Weapons Program records document 209 separate UAP sightings at Sandia Base, New Mexico — the nation's primary nuclear weapons facility — between 1948 and 1950. Witnesses, primarily military personnel, described orbs that performed high-speed maneuvers and, in several cases, appeared to explode. The proximity to classified nuclear infrastructure was assessed as a national security concern. The files are part of the May 2026 Pentagon archive release.

Chiles-Whitted Eastern Airlines Rocket Object

◎Montgomery, Alabama, USA

Two experienced Eastern Airlines captains reported a cigar-shaped, double-decked object with a blazing exhaust that passed within 700 feet of their DC-3 at 700 mph over Montgomery, Alabama. Project Sign analysts concluded it was the 'most credible' UAP report of 1948 and drafted a classified estimate attributing it to extraterrestrial origin.

Los Alamos Green Fireballs — Nuclear Site Overflights

◎Los Alamos, New Mexico, USA

A series of brilliant green fireballs overflew the Los Alamos and Sandia nuclear facilities repeatedly throughout 1948–1949. The Air Force, FBI, and nuclear scientists concluded the objects did not match meteor or ball lightning behavior. Dr. Lincoln La Paz formally assessed them as artificial in a classified report to the FBI.

Project Sign — USAF First Official UAP Investigation

◎Wright-Patterson AFB, Dayton, Ohio, USA

Project Sign was the US Air Force's first official UAP investigation program, established January 22, 1948. Its analysts produced a classified 'Estimate of the Situation' that concluded the best UAP evidence supported an extraterrestrial hypothesis. Air Force Chief of Staff General Hoyt Vandenberg rejected the estimate and ordered it destroyed. The original report no longer exists; surviving copies were found in 1969.

Eastern Airlines Chiles-Whitted Rocket Encounter 1948

◎Montgomery, Alabama airspace

Eastern Airlines Captain Clarence Chiles and First Officer John Whitted observed a rocket-shaped craft pass their DC-3 at close range near Montgomery Alabama. The craft had two rows of square windows with brilliant blue-white light and left a 50-foot orange-red exhaust trail. Project Sign analyzed the case and some analysts considered it important enough to propose the 'Estimate of the Situation' hypothesis of extraterrestrial origin — a document reportedly destroyed by Air Force Chief of Staff General Hoyt Vandenberg.
