Glowing objects in the sky, mysterious military reports, and files kept locked away for decades: the newly released UFO documents provide insight into some of the strangest cases of recent decades.
A key focus of these historical files is the reports from Allied pilots during the final months of World War II.
They described bright flying objects moving at high speeds that accompanied their aircraft over Germany.
These phenomena later became known as “Foo Fighters.”
The files state literally:
On the night of December 22, 1944, two lights rose from the ground near an aircraft of the 415th Night Fighter Squadron, climbed to its altitude, positioned themselves behind its tail for around two minutes, and then “detached again” — according to the crew, always under “full control.” Ground radar confirmed that there were no enemy aircraft nearby.
Such encounters were repeatedly reported. Over a period of six weeks, crews from the 415th Squadron operating over Germany and France reported red, green, and orange lights flying in formation with their aircraft, performing evasive maneuvers, and approaching as close as approximately 30 meters. The pilots called these phenomena “Foo Fighters.”
The British Air Ministry examined the reports and concluded in a classified memorandum in March 1945 that “the whole matter remains a mystery.”
Despite this, pilots also reported seeing an aluminum cylinder approximately 3.6 meters long at an altitude of around 2,700 meters. When fired upon by the aircraft, the object partially lost its shape and displayed a glowing red effect but did not break apart. Intelligence classified it as possibly a German “bulletproof bomb.”
No one was able to provide a clear explanation for the mysterious lights. The file remained classified for 80 years.
The military considered several possible explanations. One theory was that they could have been previously unknown German secret weapons or experimental aircraft using new rocket or jet propulsion systems. However, investigations found no convincing evidence to support this.
Declassified FBI Reports: “Nazi UFOs”
The released material also includes historical FBI documents from the 1940s and 1950s containing reports about alleged German developments of disc-shaped flying devices. Some of these references are linked to possible secret research projects in the Berlin area and regions near the Austrian border.
However, these reports do not come from confirmed technical investigations or verified military files. Instead, they are mainly based on statements from informants, rumors, and intelligence information collected in the immediate aftermath of the war. Therefore, they mostly reflect the leads that authorities chose to investigate at the time.
The documents do not provide evidence that Nazi Germany actually developed operational “flying discs” with extraordinary flight capabilities. Historians place many of these stories within the context of speculation surrounding German secret weapons, psychological warfare, and Allied efforts to obtain advanced German technology.
Memorandums from SHAEF and the British Air Ministry from 1944/45 repeatedly describe red, green, and orange lights that appeared to move in a controlled manner, fly alongside aircraft formations, and in some cases approach aircraft at close distances.
Glowing Shapes and Unknown Flight Maneuvers
Later investigations, such as the U.S. Air Force’s Project Blue Book (1947–1969), also documented a wide range of sightings. Observers described glowing geometric shapes, disc-shaped or arrow-shaped objects, and phenomena without visible wings, rotors, or conventional propulsion systems.
Some reports described objects that appeared to hover motionless in the air, suddenly accelerate, or perform flight maneuvers that were difficult to reconcile with aviation technology known at the time.
Alongside historical documents, archives contain numerous files from more recent years. Since the public disclosure of the Pentagon’s AATIP (Advanced Aerospace Threat Identification Program) in 2017, the United States has expanded investigations into so-called UAPs (Unidentified Anomalous Phenomena).
The Department of Defense has created new structures to record and evaluate unusual observations by military personnel. The Pentagon has also released previously classified recordings of unidentified flying objects, including videos captured by Navy pilots in 2004 and 2015, whose phenomena initially could not be clearly identified.
Some documents also report physical effects experienced by military personnel after close encounters, including nausea, headaches, skin irritation, or neurological symptoms. What lies behind these unexplained observations remains debated today. Explanations range from known technological phenomena and misinterpretations to much broader hypotheses.
This increased transparency in handling Pentagon files is also being closely watched in Europe. Security and defense experts are following U.S. initiatives, as unusual phenomena in airspace are increasingly viewed as a potential security and intelligence concern.
Between History and Speculation
The newly released files highlight one key point above all: interest in unusual aerial phenomena dates back a long time and is closely connected with historical events such as World War II.
Germany appears in the documents, but the files provide no evidence of extraterrestrial spacecraft or secret German “flying discs.”
Instead, they document how armed forces and intelligence agencies have spent decades attempting to explain unusual observations — and how persistent myths have emerged from these events and continue to exist today.
