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.

Fukui, Japan, on July 19, 1945:

Case number:

ACUFO-1945-07-19-FUKUI-1

Summary:

In the XXIst Bomber Command Tactical Mission Report for Mission 277, flown on July 19, 1945, on Fukui, Japan, it is said that a B-29 of the 58th Wing reported a "round white light" that "approached rapidly from behind, grew smaller and then disappeared before any outline could be distinguished."

Though similar or even less strange reports were picked up in the 2000's in various ufology sources, this one was not.

2. Mission 277, Fukui, 58th Wing:

a. A total of 8 aircraft were seen. Two fighters acted as pacers.

b. A round white light approached 1 B-29 rapidly from behind, grew smaller and then disappeared before any outline could be distinguished.

Aircraft information:

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.

B-29.

Discussion:

Map.

The case does not seem strange to me, and I would not have included it in my catalog if it were not for the fact that cases as strange or less strange have indeed been included in ufological sources; there will therefore be no reason for this one to be ignored.

That said, as with some of the other cases, it is possible, although not proven, that the light was a searchlight on an enemy aircraft.

American aviators would of course have interpreted a normal aircraft light as such, but it turns out that sometimes Japanese planes had been equipped additionally with a real searchlight, and it is then logical to find reports of this kind without the interpretation being given immediately.

In other reports, it was estimated that the Japanese had equipped some of their planes with powerful headlights or searchlights in order to designate the B-29 as targets for their fighter planes or their flak.

The report says the light became smaller and then disappeared before any outline could be made out; this happening while the thing would have been approaching from behind. We can think that this apparent reduction in size despite the approach would be due to a heading of the enemy plane which would have deviated towards the side, the searchlight then becoming less and less directly aimed towards the B-29.

Evaluation:

Possible enemy aircraft with searchlight.
