- When did the Danish Air Force release its UFO archive?
- Flyvetaktisk Kommando published the Flyvevabnet UFO archive on January 29, 2009 on Forsvaret.dk. The release comprises four parts totaling approximately 329 pages of standardized Spoergeskema (questionnaire) reports using form RCS CHODDEN INT-20209 (Form 3622).
- What types of observations are documented in the Danish archive?
- The questionnaires record Danish military and civilian observations of 'rockets and similar' phenomena across multiple decades. A December 2002 report south of Koege logs a greenish-tinged yellow light watched for half an hour starting at 0400Z, moving in multiple directions 'ikke som et fly' (not like a plane). A November 1987 report from the Bjerringbro area describes a tilted structure with red and white lights at low altitude.
- What is the corpus coverage?
- Four files cover the full archive: intl-dk-flyvevabnet-2009-part-1 through part-4, spanning pages 1-329 of the 2009 Flyvevabnet release.
