Kenneth Arnold UFO sighting

On June 24, 1947, Arnold was flying from Chehalis, Washington, to Yakima, Washington, in a CallAir A-2 on a business trip. He made a brief detour after learning of a $5,000 reward (equivalent to $ today) for the discovery of a U.S. Marine Corps C-46 transport airplane that had crashed near Mount Rainier. A few minutes before 3:00 p.m. (15:00) at about in altitude and near Mineral, Washington, Arnold had given up his search for the downed airplane and began heading eastward towards Yakima, when he noticed a bright flashing light, similar to sunlight reflecting from a mirror. Worried that he might be dangerously close to another aircraft, Arnold scanned the skies around him but all he could detect was a DC-4 to his left and behind him, about away, with the assistance of ground radar. The objects quickly approached Mount Rainier and then passed in front of it, usually appearing darker in profile against the bright white snowfield covering the peak, but occasionally still giving off bright light flashes as they flipped around erratically. Arnold reported at times the objects appeared so thin and flat, they were practically invisible. According to Jerome Clark, Arnold described them as a series of objects with convex shapes, though he later revealed that one of the objects differed from the other eight by being crescent-shaped. Several years later, Arnold would state he likened their movement to saucers skipping on water, without comparing their actual shapes to saucers, Arnold said the objects were grouped together, as Ted Bloecher writes, "in a diagonally stepped-down, echelon formation, stretched out over a distance that he later calculated to be five miles". Though they were moving on a more or less level horizontal plane, Arnold said the objects weaved from side to side ("like the tail of a Chinese kite" as he later stated), darting through the valleys and around the smaller mountain peaks. They would occasionally flip or bank on their edges in unison as they turned or maneuvered causing almost blindingly bright or mirror-like flashes of light. The encounter gave him an "eerie feeling", but Arnold suspected he had seen test flights of a new U.S. military aircraft. Arnold refueled his airplane and continued on his way to an air show in Pendleton, Oregon. Reporters assessed Arnold as highly-credible when they interviewed him at length; as historian Mike Dash wrote: Speaking to a reporter for the Associated Press, Arnold told him: "This whole thing has gotten out of hand. I want to talk to the FBI or someone. Half the people look at me as a combination of Einstein, Flash Gordon and screwball. I wonder what my wife back in Idaho thinks." Corroboration '') On July 4, 1947, the Oregon Journal in Portland, Oregon reported receiving a letter from an L. G. Bernier of Richland, Washington (about east of Mount Adams and southeast of Mount Rainier). Bernier wrote that he saw three of the strange objects over Richland flying "almost edgewise" toward Mount Rainier about one half-hour before Arnold. Bernier thought the three were part of a larger formation. He indicated they were traveling at high speed: "I have seen a P-38 appear seemingly on one horizon and then gone to the opposite horizon in no time at all, but these disks certainly were traveling faster than any P-38. [Maximum speed of a P-38 was about 440 miles an hour.] No doubt Mr. Arnold saw them just a few minutes or seconds later, according to their speed." The previous day, Bernier had also spoken to his local newspaper, the Richland Washington Villager, and was among the first witnesses to suggest extraterrestrial origins: "I believe it may be a visitor from another planet." About west-northwest of Richland in Yakima, Washington, a woman named Ethel Wheelhouse likewise reported sighting several flying discs moving at fantastic speeds at around the same time as Arnold's sighting. When military intelligence began investigating Arnold's sighting in early July (see below), they found yet another witness from the area. A member of the Washington State forest service, who had been on fire watch at a tower in Diamond Gap, about south of Yakima, reported seeing "flashes" at 3:00 p.m. on the 24th over Mount Rainier (or exactly the same time as Arnold's sighting), that appeared to move in a straight line. Similarly, at 3:00 p.m. Sidney B. Gallagher in Washington state (exact position unspecified) reported seeing nine shiny discs flash by to the north. Other Seattle area newspapers also reported other sightings of flashing, rapidly moving unknown objects on the same day, but not the same time, as Arnold's sighting. Most of these sightings were over Seattle or west of Seattle in the town of Bremerton, either that morning or at night. The primary corroborative sighting, however, occurred ten days later (July 4) when a United Airlines crew over Idaho en route to Seattle also spotted five to nine disk-like objects that paced their plane for 10 to 15 minutes before suddenly disappearing. Arnold talks of possible non-earthly origins On July 7, 1947, two stories came out where Arnold raised the topic of possible extraterrestrial origins, both as his opinion and those who had written to him. In an Associated Press story, Arnold said he had received quantities of fan mail eager to help solve the mystery, none of it calling him a "screwball". Many of the writers, like a doomsday preacher Arnold spoke of, placed a religious interpretation on his sighting. But others, he said, "suggested the discs were visitations from another planet." Arnold added he had purchased a movie camera, which he would now take with him on every flight, hoping to obtain photographic proof of what he had seen. In the other story, Arnold was interviewed by the Chicago Times: In an Associated Press story from July 19, Arnold reiterated his belief that if they weren't Army, then they were extraterrestrial: In April 1949, in a skeptical article in the Saturday Evening Post titled "What You Can Believe About Flying Saucers", Arnold was likewise quoted: In 1950, broadcaster Edward R. Murrow interviewed Arnold, who stated that since June 1947 he had had three additional sightings of nine spacecraft. ==Publicity and origins of term "flying saucer"==

Arnold's account was first featured in a few late newspaper editions on June 25, appeared in numerous U.S. and Canadian papers (and some foreign newspapers) on June 26 and thereafter, often on the front page. Without exception, according to Bloecher, the Arnold story was initially related with a serious, even-handed tone. The first reporters to interview Arnold were Nolan Skiff and Bill Bequette of the East Oregonian in Pendleton, Oregon on June 25, and the first story on the Arnold sighting, written by Bequette, appeared in the newspaper the same day. The term appears Starting June 26 and June 27, newspapers first began using the terms "flying saucer" and "flying disk" (or "disc") to describe the sighted objects. Thus the Arnold sighting is credited with giving rise to these popular terms. The actual origin of the terms is somewhat complicated. Jerome Clark cites a 1970 study by Herbert Strentz, who reviewed U.S. newspaper accounts of the Arnold UFO sighting, and concluded that the term was probably due to an editor or headline writer: the body of the early Arnold news stories did not use the term "flying saucer" or "flying disc." However, some earlier stories did in fact credit Arnold with using terms such as "saucer", "disk", and "pie-pan" in describing the shape. (see quotations further below) Bequette interview Years later, Arnold claimed he told Bill Bequette that "they flew erratic, like a saucer if you skip it across the water." Arnold felt that he had been misquoted since the description referred to the objects' motion rather than their shape. Thus Bequette has often been credited with first using "flying saucer" and supposedly misquoting Arnold, but the term does not appear in Bequette's early articles. Instead, his first article of June 25 says only, "He said he sighted nine saucer-like aircraft flying in formation..." The next day in a much more detailed article, Bequette wrote, "He clung to his story of shiny, flat objects racing over the Cascade mountains with a peculiar weaving motion 'like the tail of a Chinese kite.' ...He also described the objects as 'saucer-like' and their motion 'like fish flipping in the sun.' ...[Arnold] described the objects as 'flat like a pie-pan and somewhat bat-shaped'." It wasn't until June 28 that Bequette first used the term "flying disc" (but not "flying saucer"). A review of early newspaper stories indicates that immediately after his sighting, Arnold generally described the objects' shape as thin and flat, rounded in the front but chopped in the back and coming to a point, i.e., more or less saucer- or disk-like. He also specifically used terms like "saucer" or "saucer-like", "disk", and "pie pan" or "pie plate" in describing the shape. The motion he generally described as weaving like the tail of a kite and erratic flipping. For example, in a surviving recorded radio interview from June 26, 1947, made by reporter Ted Smith, United Press correspondent in Pendleton, and aired on KWRC, the local radio station of Pendleton, Arnold described them as looking "something like a pie plate that was cut in half with a sort of a convex triangle in the rear." His motion descriptions were: "I noticed to the left of me a chain which looked to me like the tail of a Chinese kite, kind of weaving... they seemed to flip and flash in the sun, just like a mirror... they seemed to kind of weave in and out right above the mountaintops..." ==Military investigation of Arnold story==

(AAF) intelligence, dated July 12, 1947, which includes annotated sketches of the typical craft in the chain of nine objects The first investigation of Arnold's claims came from Lt. Frank Brown and Capt. William Davidson of Hamilton Field in California, who interviewed Arnold on July 12. Arnold also submitted a written report at that time. Regarding the reliability of Arnold's sighting, they concluded: Others were less impressed. First Lt. Hal L. Eustace of the Army Air Corps, in a declassified July 1947 intelligence report, said that Arnold "seems to be reasonably well balanced, although excitable", describing Arnold's report as a case of "silly season episodes". ==Widespread UFO reports after Arnold sighting==

In the weeks that followed Arnold's June 1947 story, at least several hundred reports of similar sightings flooded in from the U.S. and around the world—most of which described saucer-shaped objects. ==Skeptical explanations==

In an article published in The Minneapolis Star two days after the sighting, officials at McChord Army Air Field, about 75 air miles from the mid-point of the peaks of Mount Rainier and Mount Adams, "theorized that the only planes coming near the description are the fast P-80s." The officials at McChord added that March Field, California was the closest airfield with P-80s based on it. March Field was about 600 air miles (about an hour's journey in a P-80) from the midpoint of the peaks of Mount Rainier and Mount Adams. The commander of the White Sands Proving Ground in New Mexico, Lieutenant Colonel Harry R. Turner, also told reporters that Arnold's sighting was consistent with the appearance of jet airplanes. When police officers and others in Portland, Oregon reported "flying disks" on the Fourth of July, Army officials responded "by pointing out that 24 P-80 fighters and six bombers flew over the city about the time the 'discs' were reported." Steuart Campbell has said that the objects Arnold reported could have been mirages of several snow-capped peaks in the Cascade Range. Campbell's calculation of the objects' speed determined that they were travelling at roughly the same speed as Arnold's plane, indicating that the objects were in fact stationary. Mirages could have been caused by temperature inversions over several deep valleys in the line of sight. Philip J. Klass cited an article by Keay Davidson of the San Francisco Examiner in arguing that Arnold might have misidentified meteors on June 24, 1947. James Easton was one of several skeptics to suggest that Arnold may have misidentified American white pelicans: the birds live in the Washington region, are rather large (wingspans of over are not uncommon), have a pale underside that can reflect light, can fly at rather high altitudes, and can appear to have a somewhat crescent-shaped profile when flying. Donald Menzel's explanations Donald Menzel was a Harvard astronomer and one of the earliest UFO debunkers. Over the years, he offered several possible explanations for Arnold's 1947 UFO sighting. • In 1953, Menzel suggested that Arnold had seen clouds of snow blown from the mountains south of Mount Rainier. • In 1963, Menzel proposed that Arnold had seen orographic clouds or wave clouds. • In 1971, Menzel said that Arnold may have merely seen spots of water on his airplane's windows. ==References==
