ACUFO:

ACUFO is my comprehensive catalog of cases of encounters between aircraft and UFOs, whether they are "explained" or "unexplained".

The ACUFO catalog is made of case files with a case number, summary, quantitative information (date, location, number of witnesses...), classifications, all sources mentioning the case with their references, a discussion of the case in order to evaluate its causes, and a history of the changes made to the file.

Okinawa, Japan, in August 1945:

Case number:

ACUFO-1945-08-01-OKINAWA-1

Summary:

At the end of the 1990s, in a catalog of encounters between pilots and UFOs, ufologist Dominique Weinstein noted a case of August 1, 1945, above Okinawa, Japan:

H. B. Kreer, pilot of a US Marine F-4U fighter plane flying at 30,000 meters, had seen "an unidentified object."

Weinstein gave no details, and indicated that his primary source was a letter from the witness to astronomer and ufologist Joseph Allen Hynek, a letter stored in the file of his ufology group CUFOS.

I found a case on the NICAP ufology website that may or may not be the same, published in 2017:

It is noted that in August 1945, in Okinawa, Japan, a cigar-shaped UFO, metallic, without visible markings or openings, and measuring 35 to 50 feet in length, was seen; this is said to come from the 2007 book "Strange Company - Military Encounters with UFOs in World War II" by Keith Chester.

I can confirm that the witness, Henry B. Kreer, was indeed a US Navy Marines pilot stationed in Okinawa at the time of the sighting, but I have been unable to locate his letter to Dr. J. Allen Hynek.

August 1st, 1945

Over Okinawa, Japan

H. B. Kreer, pilot of a US Marine F-4U fighter flying at 30,000 saw an unidentified object.

Aug. 1945; Okinawa, Japan

Cigar-shaped, metallic, and without markings or visible openings, and 35 to 50 feet in length. (Page 189-190 Ref.1)

The reference 1 is described at the end of the document as "Strange Company (2007), Keith Chester".

Aircraft information:

The Chance Vought F4U "Corsair" (photo below) was a very efficient American fighter plane, one of the best-known aircraft of the Second World War, capable of operating from aircraft carriers, used during World War II in the Pacific, serving with both the US Navy and US Marine Corps Aviation.

F4U.

I found some information about the witness:

Carte.

Henry B. Kreer, aka Henry Blackstone Kreer, aka "Pete" Kreer, (photo above) was born on September 2, 1923 in Pittsburg, USA, and died on July 15, 2001, at his home in Glenview, Illinois, USA.

He graduated from New Trier High School in 1941, having lettered in football, basketball and tennis. He attended Princeton University School of Architecture until he enlisted as a naval aviation cadet in the Navy's V5 program, which led to being a fighter pilot in the U.S. Marine Corps.

Promoted to captain in the Marine Corps, he participated in campaigns of Midway, Guam, and Okinawa, for which he received the Distinguished Flying Cross. He served as a squadron leader in VMF 314 for an element of fighter pilots who were stationed near Okinawa during World War II. He flew numerous missions protecting the U.S. naval fleet from Japanese kamikaze pilots and supporting the ground troops on Okinawa. In 1945, he briefly served as a flight instructor before returning to Winnetka, where he was a member of the Marine Corps Reserve, flying out of the Glenview Naval Air Station.

He then attended Northwestern University, the university to which ufologist J. Allen Hynek, Air Force UFO consultant, was attached as an astronomer.

What I failed to find is the letter he is said to have written to Dr. Allen Hynek. It does not seem to appear on either the CUFOS Website not the Project 1947 Website.

As can be seen, in this file, after the [dwn1] source, I noted a report from the NICAP Website [nip1]. It must be understood that I am suspecting, but not certain, that the latter concerns the same case.

So far, this looks like y very interesting and high strangeness case, but information is missing.

Evaluation:

Possible extraterrestrial craft, insufficient information.
