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.

Honshu, Japan, in 1945:

Case number:

ACUFO-1945-00-00-HONSHU-1

Summary:

In the 1980's, Dr. Louis Winkler, an astronomer at the Pennsylvania State University, compiled for the Fund for UFO Research (FUFOR), USA, a catalog of pre-1947 "UFO-like phenomena".

One of the cases he noted was that in 1945, on the main siland of Honshu, Japan, "...Some airplanes were approached from behind and then paced by six round, silver objects. The objects were obviously under intelligent control and sensitive to every move of the airplanes."

Winkler gave as source "IUFOM (1978 n.2)", a publication I never found.

[Ref. lwr1:] DR. LOUIS WINKLER:

1945/Honshu, Japan/IUFOM (1978 n.2)

Some airplanes were approached from behind and then paced by six round, silver objects. The objects were obviously under intelligent control and sensitive to every move of the airplanes.

Aircraft information:

There is no information on the aircraft. But they were very likely B-29's.

The Boeing B-29 "Superfortress" was the heaviest bomber of the US Army Air Force, used in operations from May 8, 1944 and on. Its maximum speed was 574 km/h.

Its defensive armament was 12 Browning M2 12.7 mm machine guns.

Discussion:

Honshu is the largest island of Japan, formerly known in the West as "Hondo".

So far, I found no information at all about "IUFOM" No. 2 of 1978, the source indicated by Dr. Louis Winkler. It must obviously be a bulletin about UFOs, probably from the USA.

The credibility of this source, and therefore of the report, is in question.

Evaluation:

Unknown credibility.
