Case number:

ACUFO-1947-07-04-MOSCOW-1

Summary:

The newspaper The Daily Astorian for July 5, 1947 reported on page 1 that a "flying disc" has been "seen by CAA Officials."

The newspaper reported that Irving C. Allen, former city attorney of Seaside, now airport operation and management chief of the CAA's 7th region, saw a "flying saucer" east of Moscow, Idaho, on July 4, 1947, at 10:30 a.m. when he was flying from Coeur d'Alene to Lewiston.

Allen said the "flying saucer" was first sighted by William Farrell, assistant district airports manager or the CAA, who was a passenger in the plane.

Allen said that the flying object traveled in a northerly direction in a wavering, flitty way, it "bounced along," but on a regular course. By checking its course against that of his own plane and two planes which were following him, Allen and Farrell roughly computed the speed of the saucer at 300 miles an hour. His plane was then flying at about 4000 feet and the saucer appeared to be at a somewhat higher elevation.

Allen related that the object was in sight for five minutes after it was discovered by Farrell.

He is quoted saying:

"I could have taken a picture of the saucer. It was remarkably white and larger than the largest plane."

Allen said he saw no trail of vapor, and no wings on the disc; which he observed closely for five minutes.

Other newspaper reported the sighting; in The Kitsap Sun for July 5, 1947, Allen said that his assistant William Allen also observed the object. The Chicago Daily News for July 5, 1947, indicated that Allen was in a light plane.

The Pittston Sunday Dispatch for July 6, 1947, specified that the object "proceeded on a northerly course at uniform altitude with a wavering flight", and that when Allen could have taken a picture of it, it was passing several miles in front of his plane.

This sighting report was summarized by US ufologist Ted Blocher in 1967, and several other since.

Flying Disc Seen by CAA Officials

Irving C. Allen, former city attorney of Seaside, saw a 'flying saucer" east of Moscow, Ida., Friday 10:30 when he was flying from Coeur d'Alene to Lewiston.

Allen, who is now airport operation and management chief of the CAA's seventh region, reported here today that the "saucer" first sighted by William Farrell, assistant district airports manager or the CAA, who was a passenger in the plane.

***

Allen said that the flying object traveled in a northerly direction in a wavering, flitty way but on a regular course. By checking its course against that of his own plane and two planes which were following him, Allen said that he and Farrell roughly computed the speed of the saucer at 300 miles an hour. His plane was then flying, at about 4000 feet and the saucer appeared to be at a somewhat higher elevation.

***

Allen related that the disc-like flying mystery was in sight for five minutes after it was discovered by Farrell.

"I could have taken a picture of the saucer," Allen said. It was remarkably white and larger than the largest plane, the former city attorney said. Allen saw no trail of vapor nor did he see wings on the disc. His description of its flight, which he observed closely for five minutes, was that it bounced along."

***

Allen indicated that veteran airmen do not regard the flying disc as a fragment [sic, figment] of Imagination. His description of the disc is similar to that given by people of the Fort Stevens annex who sighted a "plugged doughnut" over the fort several days ago.

Whatzits of Sky Puzzle Nation

The strange "flying discs" reported over West Coast cities since June 26 were reportedly photographed yesterday and chased by a United Airlines passenger plane near Boise, Idaho, but their identity remained a mystery today.

Coast guardsman Frank Ryman, 27, had a picture today snapped from the front porch of his home in Seattle which authorities hoped would clear up the mystery of the flying saucers.

Ryman said an enlargement of the shot made yesterday afternoon at 5:30 o'clock showed a "white


WEDGEWOOD, England. - Two saucers reported here today that they have seen men flying through the air at high speed.


saucer" that was neither an airplane, a cloud or a silver balloon.

The pilot and co-pilot of the airlines plane said they turned their aircraft off course and chased a "strange object" for 15 miles before it outdistanced them or disintegrated in the dusk.

Capt. R. J. Smith and Second Officer R. E. Stevens, both of Seattle, said, "We can definitely say that what we saw was not smoke, not a cloud, and not another airplane."

Two Portland, Ore., police scout cars three miles apart notified their headquarters by radio at 1:15 p.m. yesterday that they had sighted a group of strange objects weaving in a "playful manner" 10,000 feet above the ground over the southern suburbs of Portland.

The discs were reported seen over numerous other communities of the northwest and a man in Pin Bluff, Ark., said he saw a flying object "about the size and color of a wash tub."

The army said no attempt had been made to pickup the discs with radar equipment, explaining that radar facilities were only used for training purposes in this area at present.

At Decatur, Ill., several motorists said they parked alongside a highway Thursday night to watch "mysterious, round, flat objects" fly across the sky. Some said they appeared as large as airplanes.

For the first time, reports of "flying discs" came from the east. Something round was sighted at Philadelphia traveling at about the speed of the wind below a cloud layer.

Three groups of "flying discs" were seen by 60 picnickers at Twin Falls (Idaho) City Park within 20 minutes late yesterday, A. E. Mitchell, of Goose Creek, Texas, reported today.

Mitchell, visiting in Twin Falls, said that a formation of seven mysterious objects were seen about 2:50 p.m. by seven persons.

He said that 10 minutes later, 30 picnickers saw another group of nine or 10 discs whirling through the air. At 3:10 p.m. Mitchell said that a third "flight" of 18 "flying saucers" were seen by 60 persons who had been scanning the sky after the first two flights.

Mitchell said that the group of seven was in V-formation, but the other two groups were circling and diving in loose formation.

Irving C. Allen, Northwest CAA official, reported seeing one of the objects Friday morning east of Moscow, Idaho, as he was flying a plane between Coeur d'Alene and Lewiston, Idaho.

The bright, shiny craft, larger than an airplane, was flying at a high rate of speed and was "swaying" slightly, Allen said.

"There was no vapor trail or noise and with William Allen, my assistant, we were able to observe it for fully five minutes," Allen said.

U. S. naval observatory officials concluded unofficially today that the mysterious "flying saucers" are not, at least, astronomical phenomena.

An official said the observatory's unofficial decision was based on descriptions of the strange flying objects since none of their astronomers had seen them.

Meanwhile, both the army and navy confessed themselves unable to give an explanation for the reported objects. The army began an investigation Thursday.

Although there were some reports the saucers might have been a new-type navy plane, "The Flying Pancake," the navy said it had only one such plane and that was in Hartford, Conn.


LANGENDORF, Germany. - A bakery, reported here today that six dozen pieplates are missing.

17 STATES SIGHT 'FLYING DISKS'

Objects Noted at Decatur
Mystery Grows Throughout U.S.

The nation's perplexity over disks reported spinning through the skies deepened today in the wake of Fourth of July reports from virtually all parts of the country.

No convincing explanation was offered to fit the observations, which spanned the nation from the Pacific to the Atlantic and down to the Gulf of Mexico.

The reports came from at least 17 states and Prince Edward Island, Canada.

In the Midwest, the disks were reported seen in Illinois, Indiana, Michigan and Ohio.

* * *

TWO HUNDRED persons in one group and 60 in another saw them in Idaho. Others reported them in Washington, Oregon, California, Colorado, and Utah in the West.

For the first time, Eastern states had reports, too. They came from Pennsylvania, New Jersey and Maine.

On the list in the South were Louisiana, Georgia, South Carolina and Kentucky.

That the end was not yet became apparent today when Donald Dwiggins, a salesman of Glendale, Calif., said he saw four - "changing shape as they flew" - over the southern California city.

* * *

CLAUDE PRICE of Springfield, Ill., concession superintendent of the Illinois State Fair, said several autoists parked along Route 36 near Decatur Thursday night to watch "mysterious round, flat objects" fly across the sky.

He said the objects looked about as big as airplanes.

The most detailed report came from the entire crew of a Boise-to-Seattle United Air Lines plane who said they saw nine of the disks over Emmett, Idaho.

* * *

CAPT. E. J. SMITH said his co-pilot, Ralph Stevens, blinked the transport's landing lights in the belief the disks were other aircraft. Smith and Stevens said there was no response from the mysterious objects.

Blinking landing lights during a night flight is a pilot's signal of warning to other aircraft that a plane is flying in the same area.

* * *

SMITH SAID he and Stevens saw the disks eight minutes after takeoff from Boise, flying in what appeared to be a "loose formation."

They called Marty Morrow, stewardess, to the cockpit to verify that they were actually seeing the disks. She agreed they weren't seeing a mirage.

* * *

A LOS ANGELES pilot and his companion said they were "scared silly" when they saw what they thought was one of the flying saucers moving swiftly north by northeast at 7,000 feet, some 2,000 feet above their plane.

At Astoria, Ore,., Irving C. Allen, Pacific Northwest Civil Aeronautics Administration official, reported seeing a disk Friday morning East of Moscow, Idaho, as he was flying a light plane be-

tween Coeur d'Alene and Lewiston, Idaho. Thirteen persons viewed two of them at noon above Clifton, Colo., yesterday, Mrs. Cora Burks reported there.

In Seattle, Frank Ryman, a coastguardman, said he took pictures of "flying disks" early last evening after excited neighbors told him they were in the sky.

* * *

THE PICTURES showed a tiny light spot, about the size of a pinhead, against the dark background of the sky. The mysterious objects also were reported over Utah last evening for the second time in two weeks.

Several residents southwest of Port Huron, Mich., reported seeing a number of the "flying disks" criss-crossing the sky last night and moving northward.

* * *

TWO MEN in Akron, Ohio, and two in Delaware, Ohio, also reported seeing the saucers.

At Akron, Dr. Forrest Shaver said the thing he saw "looked like a balloon with a light inside" while Harry E. Hoertz called it a "light with a propelling device."

Dan Kelly, program director for Radio Station WRDO at Augusta, Me., said he and a friend saw about a dozen grayish round disks "flying in a straight line very high above the city."

* * *

A NEW ORLEANS saleswoman, Miss Lillian Lawless, reported seeing one of the disks over Lake Pontchartrain last night.

Weird Reports Of Seeing Discs Starts Jitters

Army Officials Deny Any Knowledge Of "Eerie" Display

Seattle, Wash., July 6 (INS) - Weird gyrations of "Flying Discs" reported by competent witnesses from Denver to Seattle stirred the nation today in a manner reminiscent of Orson Welles' "Man From Mars" jitters.

Hysteria that greeted Welles' faked radio broadcast was lacking in the factual accumulation of testimony to the long list of observers.

The excitement started June 24 when Kenneth Arnold, Boise flying businessman, first sighted the discs flying over Southwest Washington at a speed he estimated at 1200 miles an hour.

Washington, July 5 (INS) - The Army Air Forces-Custodian of the Army's Aerial Ordnance program-tonight disclaimed any knowledge of where the "Flying Discs" originated.

Capt. Tom Brown, AAF information officer, told newsmen:

"This is definitely not an air forces experiment. We absolutely do not know what these Flying Discs are. In fact, we wish we did, but we're just as mystified as everyone else."

Dan J. Whelan and Duncan Underhill, both of Hollywood, said a Disc "scared them silly" while they were flying in a private plane near Santa Monica.

"The devilish Disc was at 700 feet, about 2000 feet above us. It was traveling 400 to 500 miles an hour. It was not spinning, but looked exactly like a skeet (trapshooting target). We'd say it was about 40 to 50 feet in diameter."

Others who saw the Discs said:

"It appeared as if some unseen juggler were keeping them in the air. They finally vanished in the direction of Catalina Island."

Mrs. Verna Edwins said a "barrel-shaped Disc" sputtered over her home at 4 p.m. yesterday. She described it as "about 30 feet long and cream colored."

"It gave us an eerie feeling."

"I saw one of the big saucers fall over Arcadia, near the Santa Anita Racetrack, about 4 p.m., Friday."

"There is more behind this than meets the naked eye."

At Astoria, Ore., Irving C. Allen, Chief of Airports Operation and Management in the seventh region for CAA, reported today that he had sighted a "Flying Disc" for five minutes Friday at 10:30 a.m.

Allen said the object was remarkedly white and proceeded on a northerly course at uniform altitude with a wavering flight. He estimated the DISC was larger than the largest plane and that he could have taken a picture of it as it passed several miles in front of his plane.

[Ref. tbr1:] TED BLOECHER:

Ted Bloecher indicated that on July 4, 1947, Oregon, Irving C. Allen, Chief of Airports Operations and Management in the 7th Region for the Civil Aeronautics Administration, reported that he had spotted a "disc-like" object while flying southward from Coeur d'Alene to Lewiston, Idaho, in the vicinity of Moscow, at 10:30 a.m. PST.

Bloecher quoted Allen:

"The disc proceeded north across my plane's course from right to left and on a regular course. It was first spotted by my assistant manager, William Farrell, a passenger in the plane."

Allen said the object was "remarkably white" and moved north at a uniform altitude with a kind of "wavering" flight pattern. He estimated that it was "larger than the largest plane" as it crossed several miles in front of him as he was flying slightly east of Moscow. He and his passenger had it in view for five minutes.

N - 07.04 - 1030 hours, east of Moscow, Idaho

Flying from Couer d'Alene to Lewiston, pilot and passenger both CAA officials. an object flying in a northerly direction on a regular course, but without a wavering, fluttery or bouncing movement. The object was slightly above the CAA officials' plane's 4000 feet altitude and was flying about 300 mph. (Astoria, OR, ASTORIAN BUDGET, 5 July 1947.)

"N" means this is a new case not in November 1997 ACUFOE Catalogue.

Aircraft information:

The information is that the plane was a civilian light plane. There were 3 people on-board as far as is known.

Discussion:

Map.

Irving C. Allen was a former city attorney of Seaside, former school director in Astoria, and Civil Aeronautics Administration official attorney from Seattle at the time of the sighting.

The report is straightforward, the witness is credible, there were certainly two other witnesses, the observation lasted 5 minutes, it was in broad daylight, the object had no wings, it passed in front of the aircraft, its manner of flight was not ordinary, the speed confirmed by the duration of the observation rules out birds, clouds, and other balloons, there was no trail, which rules out a meteor.

Evaluation:

Possible extraterrestrial craft.
