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.

[Ref. nip1:] "THE NICAP WEBSITE":

[1944] Feb. 4, 1944; Dutch coast

One long black stationary object, similar to a small flak burst floating. (Page 59 Ref.1)

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


Date: Feb. 4, 1944

Location: Dutch coast


Summary: One long black stationary object, similar to a small flak burst floating.

Page 59 Ref.1

Aircraft information:

There is no information on involved aircraft. I can only recall that the book by Keith Chester is about UFO seen by military pilots during WWII.



Firstly, the information is obviously much too meager.

Secondly, there seems to be no strangeness in the report, in which we read that the phenomenon was "similar to a small flak burst floating".


Probable flak.
