AI-Generated Summary
A Swedish Defence Staff statistical table summarizing 713 aerial observations recorded between April and August 1947. It categorizes sightings by object type, altitude, and sound, while calculating the prevalence of light phenomena during specific periods.
This document is a statistical summary produced by the Swedish Defence Staff (Försvarsstaben) detailing observations made between April 25 and August 16, 1947. The data is organized into three primary time segments: July 9 to July 11, August 11, and 'other days'. The observations are categorized by the nature of the object—specifically light phenomena, torpedo or spool-shaped objects, objects with wings, and other forms—and further subdivided by whether they produced sound, their altitude (above 2000m, 2000-100m, or under 100m), and their flight characteristics (horizontal path, descending, or other). The table provides a total count of 713 observations across these categories. Additionally, the document calculates the percentage of reports classified as 'pure light phenomena' for the specified time intervals, noting 78% for the July 9-11 period, 87% for August 11, and 52% for the remaining days.
