1940 UFO sightings

Famous UFO Encounters of The 1940s

The 1940s were the golden age of UFO encounters and the start of the modern UFO era. These 5 UFO encounters kicked off our collective imaginations and had people looking to the skies for little green men from Mars.

Prior to this, there were scattered reports in the news of strange encounters with odd flying craft, or strange creatures, but these UFO encounters catapulted Aliens and UFOs to the forefront of American media and eventually worldwide. One thing is very clear, something changed in 1947.

Kenneth Arnold UFO Sighting (1947)

A pivotal event in the history of UFO sightings, Kenneth Arnold’s encounter near Mount Rainier in 1947 sparked widespread public interest and media attention. While flying his private plane, Arnold observed nine objects flying at incredible speeds in a formation he described as resembling “saucers skipping across water.”

His vivid description and the unusual nature of his sighting ignited a wave of similar reports across the United States, capturing the public’s imagination and coining the now-famous term “flying saucers.” The Kenneth Arnold case remains a foundational event in the ongoing discussion of unexplained aerial phenomena.

The Roswell UFO Crash (1947)

The Roswell incident stands as the cornerstone of UFO lore. In 1947, debris found on a New Mexico ranch ignited a media frenzy. The U.S. government initially identified it as a crashed weather balloon, but many believe it was a downed alien spacecraft, with the ensuing events shrouded in a government cover-up.

This incident continues to fuel speculation and conspiracy theories. It solidified Roswell’s place as a landmark UFO mystery, raising enduring questions about the potential for extraterrestrial life and the lengths governments might go to keep it hidden.

The Maury Island Incident (1947)

Harold Dahl and his son made an extraordinary claim in 1947 that they encountered six donut-shaped UFOs over Puget Sound, Washington. Dahl alleged that molten debris from the craft crashed onto his boat, injuring his son and killing his dog, raising the stakes of UFO encounters.

Adding a sinister twist, the Maury Island Incident introduced the concept of “Men in Black.” These mysterious, intimidating figures allegedly visited Dahl, threatening him with dire consequences if he revealed what he saw. This detail added another layer of intrigue and cemented the incident’s place in UFO folklore.

Foo Fighters (1944-45)

World War II pilots from both the Allied and Axis powers encountered a bizarre phenomenon: mysterious glowing orbs or lights that would seemingly follow and even interact with their aircraft. The term “Foo Fighters” emerged from a popular comic strip, adding a touch of levity to the otherwise unnerving encounters.

Despite numerous reports and investigations, the true nature of Foo Fighters remains elusive. Theories range from experimental enemy technology to natural phenomena like ball lightning or optical illusions. This enduring wartime mystery reminds us that the skies have always held unexplained sights.

The Cape Girardeau Incident (1941)


Predating the Roswell Incident, the Cape Girardeau crash of 1941 holds a significant place in UFO lore. Reverend William Huffman claimed to have been summoned to a crash site where he discovered a metallic disc and three small humanoid bodies. The story alleges that military personnel swiftly arrived, confiscating all evidence and silencing witnesses with threats.

The lack of contemporary records and reliance on later testimony make the Cape Girardeau Incident highly controversial. However, the tale persists, fueling ongoing speculation about early UFO encounters and potential government cover-ups.

The Battle For LA

In the early morning hours of February 25th, 1942, Los Angeles residents were jolted awake by a spectacle that would ignite decades of controversy. Searchlights pierced the sky, and anti-aircraft shells exploded above the city, transforming the night into a terrifying warzone. The target? Unidentified objects that triggered a massive military response.

The official explanation was a false alarm, triggered by jitters after the attack on Pearl Harbor. But many refuse to believe it. Was it a weather balloon caught in the spotlight, or something far more mysterious? The lack of a clear answer, combined with the wartime context, leaves lingering questions about what truly happened during the Battle of Los Angeles.

The Chiles-Whitted Case: Why Pilot Sightings Hold Weight

The Chiles-Whitted UFO encounter demonstrates the importance of witness credibility in UFO investigations. The detailed descriptions of a glowing, cigar-shaped object provided by experienced pilots, Clarence Chiles and John Whitted, made their sighting difficult to dismiss. Their professional backgrounds suggested they weren’t prone to misidentifying ordinary aircraft or atmospheric phenomena, leading investigators to give their report serious consideration.

The Mantell UFO Incident: A Tragic Mystery

On January 7th, 1948, Kentucky Air National Guard pilot Thomas Mantell died in a plane crash while pursuing a reported UFO. After climbing to high altitude, Mantell blacked out from oxygen deprivation, leading to a fatal crash. The incident, shrouded in speculation, highlights the inherent dangers of chasing unidentified objects and the enduring puzzle of UFO sightings.

The Trinity Incident: Was it an Early UFO Crash Cover-Up?

The Trinity case alleges a UFO crash occurred near San Antonio, New Mexico in 1947, weeks before the Roswell Incident. Witnesses recall a strange craft, small bodies, and a military retrieval operation. Decades later, researchers claim the military suppressed all evidence, suggesting a potential cover-up. Though controversial, the case fuels ongoing debate about pre-Roswell UFO encounters and possible government secrecy.

Flight 105: When Pilots Encountered the Unexplained

On July 4th, 1947, the crew of United Airlines Flight 105 experienced a chilling encounter that would leave them with more questions than answers. During their routine flight, they witnessed nine disc-shaped objects traveling in formation at incredible speeds. These objects performed maneuvers seemingly impossible for known aircraft, leaving the veteran pilots, including a decorated WWII pilot, perplexed.

The incident occurred in the immediate aftermath of the Kenneth Arnold sighting, adding to the public fascination with UFOs. Despite an official Air Force investigation, the Flight 105 sighting remains unexplained. It stands as a compelling case due to the experience of the pilots and their detailed descriptions, fueling debate and speculation to this day.

The Gorman Dogfight: A Pilot’s Aerial Battle with a UFO

In October 1948, North Dakota Air National Guard pilot George Gorman engaged in a 27-minute aerial chase with a brightly glowing unidentified object. Despite executing combat maneuvers, the object outmaneuvered Gorman’s F-51 fighter. The incident, witnessed by ground personnel, was thoroughly investigated by the Air Force and remains unexplained. It stands as a chilling reminder of the many UFO encounters that defy conventional explanation.

Other UFO Sightings Of The 1940s

While the cases above are the most famous of the UFO sightings of the 1940s, digging through UFO encounter websites like NUFORC, it is clear that more than a few people were seeing flying objects that they couldn’t identify during that time. Here are just a few intriguing cases.

Flame In The Sky Near Tacoma (1947)

A compelling eyewitness account has emerged with the potential to shed new light on a mysterious and long-debated UFO encounter. A 72-year-old Tacoma, Washington resident reported to NUFORC a detailed childhood memory of a bizarre sighting that could hold clues to the puzzling events of the summer of 1947.

The witness, approximately 10 years old at the time, describes a flame-like object suspended in the night sky. This object rotated while emitting a “loud, ugly roaring noise” before disappearing across the horizon with astonishing speed. The unusual nature of the sighting and its proximity to the Maury Island Incident raises intriguing questions.

The witness believes their experience may be connected to the Maury Island Incident. “If the noise was loud enough to bring my neighbor out of his house, maybe others saw a strange light/flame and noise…” they speculate. Their account offers a potential avenue for further investigation and could lead to the uncovering of additional witnesses, helping to piece together a clearer picture of this enigmatic event.

Golden UFOs Over Hayward, CA (1947)

Two former residents of Hayward, California reported to NUFORC a detailed account of a UFO encounter they allege occurred in June 1947. The brothers, who were children playing near their rural home, state they observed five “bright gold saucers” hovering close to them for approximately twenty minutes.

The witnesses describe the objects as seamless and glowing, emitting multi-colored gas and a hissing sound. They claim the UFOs exhibited incredible speed upon departure. Interestingly, the witnesses assert that two weeks later the same objects appeared above the Fourth of July fireworks at Lake Merritt in Oakland and were even spotlighted. They claim it even made the headlines of Oakland Tribune from that date, but I have yet to substantiate that.

1944 San Diego UFO: A Mysterious Cylindrical Craft

In 1944, two friends in San Diego witnessed a silent, silver cylindrical object moving slowly through the sky. The object, with no visible control surfaces, vanished behind clouds after a few minutes. Despite its unusual appearance, the witness kept the sighting secret for decades. This first-hand account highlights the enduring intrigue of unexplained aerial phenomena throughout history. (NUFORC sighting 38233)

WWII-Era UFO Encounter in Utah: Was it a Japanese Balloon or Something More?

During WWII, a woman and her toddler near Ft. Duchesne, Utah, witnessed a large, silvery object circle them.

This account adds another dimension to the history of UFO reports in the region and highlights the enduring mystery of unexplained aerial encounters, even during times of conflict.
