Avistamiento de UAP de Kenneth Arnold
In the Summer of 1934, in the city of Barron, Wisconsin, Coral Lorenzen was 9 years old, and witnessed a UFO craft with two of her friends.
Coral Lorenzen described looking the glowing white UFO craft as “an open umbrella without the ribs or spurs,” which glided silently through the sky, and vanished over the horizon over a period of about 20 seconds.

The "Battle" of Los Angeles was an anti-aircraft barrage fired by U.S. forces in February 1942, not a battle with an enemy, in response to widespread fear of Japanese aerial attack following Pearl Harbor.
After radar and observers spotted unidentified objects, artillery fired over 1,400 shells, causing several deaths from traffic accidents and heart attacks, damage to buildings, and widespread panic. The incident was later attributed by the United States Air Force to "war nerves," likely triggered by a lost weather balloon, stray flares, and heightened anxiety.
​
The event occurred during a tense period of World War II, shortly after the attack on Pearl Harbor, and amid fear of imminent Japanese attacks on the United States west coast.
In the predawn hours of February 25, 1942, military radar and observers reported unidentified objects over Los Angeles. ​In response, anti-aircraft batteries fired over 1,440 shells for almost two hours into the night sky. ​By dawn, it was clear that no enemy planes had attacked, and the incident was dismissed as a "false alarm" by the military.
​
Five people died, two from heart attacks and three in car accidents during the blackout and chaos of the event. Falling shrapnel from the artillery barrage struck and damaged buildings and homes. The incident exposed the widespread anxiety and "war nerves" felt by the public and military, particularly after a recent submarine attack on an oil field near Santa Barbara.
​
The event has also fueled UFO theories, particularly the idea that the objects were alien spacecraft.

During World War II, Allied pilots encountered mysterious, glowing aerial UFO objects, which were called "foo fighters" by the Smokey Stover comic strip.
These UFO objects appeared to follow aircraft, maneuver at high speeds, and never registered on radar, leading to speculation about secret enemy weapons or, later, alien craft. While initial theories suggested advanced German technology or even atmospheric phenomena like St. Elmo's fire, the UFO sightings remained unexplained, and investigations by scientists like Luis Alvarez yielded no definitive answers. More recent research suggests that plasmas, or ionized gases, could be a possible explanation, being attracted to the electrical fields of aircraft and appearing as glowing, dynamic phenomena.
Foo fighters were described as glowing, ball-like, or translucent objects or lights that appeared to follow military aircraft during missions in both the European and Pacific theaters. ​They were observed maneuvering at high speeds, sometimes in formations, and defying conventional explanations for aerial phenomena. ​Critically, the UFO objects were never detected by on-board or ground-based radar, further adding to the mystery.
Many pilots and intelligence officers initially suspected them to be new, advanced German or Japanese weapons. However, investigations after the war found no evidence to support the secret weapon theory. Renowned scientists, including Luis Alvarez, investigated the UFO sightings, but their findings remain largely inconclusive or have been kept secret.
​
In modern times, scientists have proposed that foo fighters could be a form of ionized gas known as plasma, attracted to the electrical charge of aircraft and appearing as glowing, dynamic lights. ​Some theories also suggest natural atmospheric phenomena, such as ice crystals or electrostatic discharges, like St. Elmo's fire, could be responsible for some sightings.
​
Foo fighter UFO sightings represent one of the earliest, well-documented cases of what would later be known as UFOs or UAPs. Despite extensive study and new theories, a definitive explanation for all foo fighter UFO sightings has yet to be found, contributing to their enduring place in scientific and popular interest.

A UFO object was spotted after midnight, while a B-29 bomber from the 468th United States Air Force Bomb Group, was returning from a bombing mission somewhere in Southeast Asia, targeting Japanese forces. The UFO was described as having "board wings," vibrating, and having an intense red or orange color.
​
The UFO object followed the B-29 bomber for eight minutes at a constant distance of about 500 yards, while the plane was flying at 14,000 feet. After the pilot performed evasive maneuvers, the object flew away at a 90-degree angle, accelerating quickly.
The 468th was a United States Army Air Forces unit that flew B-29 Superfortress bombers in the China-Burma-India and Pacific theaters.
​
In August 1944, the group was operating from bases in India and China, striking Japanese targets in Southeast Asia and Japan itself. The day after the UFO sighting, the group participated in a raid on the iron and steel works at Yawata, Japan.
​
Throughout 1944, Allied pilots in both Europe and the Pacific reported seeing unexplained glowing UFO orbs and lights following their aircraft. Military intelligence investigated the sightings, suspecting they might be secret German or Japanese weapons. However, Axis pilots also reported seeing similar UFO objects. No conventional explanation, such as enemy aircraft or weather phenomena, could consistently account for the strange UFO objects. The mystery was never officially resolved during the war.

The 1946 Angelholm UFO incident involves Gösta Carlsson, a 28-year old Swedish railway worker who claimed to see a UFO land in a forest clearing in the Kronoskogen Woods near Angelholm, Sweden, and encountered humanoid alien beings.
On May 18, 1946, Gösta Carlsson, reported seeing a flying saucer with a fin and support legs, along with human-like beings in tight, white flight suits. He claims one of the beings used a device to keep him at a distance.
Gosta Carlsson reported that the alien beings provided him with recipes for natural remedies, leading him to found successful companies, and become known as the "Pollen King". Gosta Carlsson's story is commemorated by a concrete UFO monument erected in the clearing in 1972, based on his detailed sketches. ​
​​
Gosta Carlsson later left his job and started the company Cernelle, producing natural medical products from bee pollen. He became a successful businessman and earned the nickname "Pollen King".
In 1972, Gosta Carlsson had a concrete UFO memorial built at the site of the alleged landing. The monument includes a one-eighth-scale model of the flying saucer and concrete circles marking the reported landing tracks, based on his original sketches.
Although the event occurred in 1946, Carlsson did not publicly discuss it until the 1970s.

​On June 21, 1947, Harold Dahl, his son Charles, and their dog Sparky were on a salvage boat near Maury Island when they allegedly encountered six donut-shaped flying UFO discs.
One UFO disc malfunctioned, descended, and dropped molten material and debris onto the boat, killing Sparky and burning Charles's arm.
​Harold Dahl claimed a man in a dark suit later warned him not to discuss the event, hinting at serious consequences if he did. ​Harold Dahl and his employer, Fred Crisman, reported the UFO incident, which was widely regarded as a hoax to sell stories to Palmer's magazine, according to one source.
​
Lt. Frank Brown and Captain William Davidson were sent to investigate the claims and collect debris. Both officers died in a plane crash near Kelso, Washington, on August 1, 1947, while returning with their findings, leading to speculation about a UFO cover-up. ​The FBI concluded the UFO incident was a hoax and the collected debris was aluminum. ​

Near sunset, a civilian reported a fairly small UAP object shaped like a "crate" that was observed from the ground, being not too high traveling north, and appeared to have various rainbow colors. At first the UAP object appeared to be reflecting the sunset, but when it changed position, it retained its color. There were no apparent means of propulsion, yet the object did not seem to "drift."There were no photos taken and no physical evidence.

Avistamiento de UAP de Kenneth Arnold
"On the evening of June 12, 1947 at 6:15 pm, a neighbor and I, returning home from another neighbors, glanced into the sky toward the west, and saw what we thought was smoke from an airplane. She mentioned that she had never seen that before, so we stopped to look and listen, thinking we would see the plane, but there was no sound, so we kept looking until we saw a tiny object from which the vapor emitting.
It was so far away we could not determine the size or even the shape. Its only identity was a glisten in the sun. We watched this for a few seconds, when from the general direction of the sun, another object shot into the sky. It followed the general direction of the first, shooting up and down before settling to a south-easterly course across the sky, where we followed them until they were only a glisten, and the vapor could no longer be seen.
After the objects were gone, we continued to look and to watch the vapor which had been left, which now looked like clouds but kept a shape, and this shape seemed to glide across the sky to the east, where there was a black streak leading to the horizon. The vapor stayed in the sky for over an hour."
Project Blue Book hypothesized that this case may have been a double-fireball meteor event, but that was never proven.

An experienced civilian pilot, Dick Rankin first sighted 10 UFO objects flying in a V formation to the east while at home, with one of the objects straggling behind. Later on, 7 more UFO objects were seen flying a V formation come back the opposite direction.
Dick was of the opinion that these objects were probably XF5U-1 "Flying Flapjack" United States military planes. This was the same conclusion from Project Blue Book.

On June 24, 1947, private pilot Kenneth Arnold claimed that he saw a string of nine, shiny, large UFO's or UAP, flying west past Mount Rainier at speeds that he estimated to be at least 1,200 miles an hour, or Mach 1.56, but maybe up to 1,700 miles an hour. He clocked the UFO's going 47 miles in 102 seconds.
The UFO objects appeared to dip and twist. Kenneth Arnold witnessed the UFO objects for 2 to 3 minutes, and they were about 25-30 miles from his aircraft. Kenneth Arnold estimated the UFO objects to be 45-50 feet long.
J. Allen Hyneck notes in this file that, "In all probability, therefore, objects were much closer than thought, and moving at definitely sub-sonic speeds."
Project Blue book concluded that, "the objects in this sighting was a mirage. Kenneth Arnold's statement concerning how smooth and crystal clear the air was, is an indication of very stable conditions which are associated with inversions, and increase the refraction index of the atmosphere."
This was the first UAP sighting in the United States, that received nationwide attention after the end of World War II. Kenneth Arnold's description of the UAP objects also led to the media creating the term "flying saucer" as a popular description for UAP in the future.​​​​​​​​​

Military observers from Maxfield, Alabama, sighted a star-like UFO object on a clear moon-lit night, moving east and then south at a great height, for about 5 to 6 minutes from the ground. The object was a little more brilliant than a star and had frequent bursts of speed, it was zig-zagging, and made no sound.
Project Blue Book concludes that this sighting could have been a synoptic weather balloon.

1st Lt. [name redacted in black] departed William Field, Arizona at 1400 Central Standard Time, in a P-51 bound for Portland, Oregon by the way of Medford, Oregon. At approximately 1515 CST, at an altitude of 10,000 feet and a speed of 285 miles per hour, and about 30 miles northwest of Lake Meade, Nevada, the Lt. observed 5 or 6 white, circular UFO objects at Four O' Clock, at an altitude of 6,000 feet.
​
The Lt. said that the UFO objects were flying very smoothly and in a close formation. The estimated size of the objects was 3 feet in diameter. The Lt. stated that he is not sure that the white objects were not birds, since the rate of closure was very fast. However, the Lt. states that he was certain the white objects were not jets or any conventional type aircraft, since he has flown both types.
​
The Lt. was very sincere in the explanation and was not the exaggerating type. He merely stated what he saw and has drawn no conclusions about what the white objects were. Project Blue Book concludes that the UFO objects were a balloon cluster.

At around 2:45 a.m., Clarence Chiles and John Whitted were flying an Eastern Airlines DC-3 when they saw a brilliant, glowing UFO object approach their plane at high speed.
​
They described the UFO object as a wingless, cigar, or torpedo-shaped craft, about 100 feet long. It had two rows of lighted windows and a powerful, reddish flame shooting out from its back. The pilots stated that the UFO object passed by their plane at high speed before pulling up sharply into a cloud with a final burst of flame. Only one passenger on the DC-3, who was awake at the time, also reported seeing a bright flash of light pass by.
​
The UFO sighting was investigated by Project Sign, the Air Force's first dedicated UFO study group. The project's investigators considered the pilots to be reliable and credible witnesses. A maintenance crewman at Robins Air Force Base in Macon, Georgia, also reported seeing an extremely bright light pass overhead at high speed around the same time, which was seen by some as corroborating the pilots' account.
​
Project Sign personnel drafted a top-secret "Estimate of the Situation" concluding the UFO object was interplanetary, but Air Force Chief of Staff Hoyt S. Vandenberg rejected the finding in October 1948, citing insufficient evidence.
​
Early investigators, including astronomer and Project Sign consultant J. Allen Hynek, suggested the UFO object was a brilliant meteor. Skeptics like astronomer Donald Menzel supported this explanation, noting increased meteor activity at the time.
​
Supporters of the meteor theory noted that the fiery tail and rapid disappearance were consistent with a fireball. However, critics pointed out that the UFO object's described movement, which included a sharp upward turn, is not characteristic of a meteor. In 1959, Project Blue Book, which was the successor to Project Sign, formally attributed this UFO incident to a meteor. However, this UFO incident remains a point of contention among UFO researchers due to the credible testimony of the experienced pilots, and the specific features they described that don't easily fit the official explanation.
