History

APRO Microfilm Reel 1 is a compilation of historical UFO reports assembled by the Aerial Phenomena Research Organization and later digitised by Steve Kaesar. The collection spans reports from as early as 1558 through to the 1950s, organised into thirteen parts covering different date ranges. APRO compiled these historical cases as part of its effort to document the phenomenon's deep historical precedent, drawing on newspaper accounts, official records, and private correspondence from across centuries.

Significance

This microfilm reel preserves APRO's historical research archive, representing one of the most comprehensive attempts by a civilian organisation to catalogue pre-modern aerial phenomena reports. The chronological span, from the sixteenth century through the early modern UFO era, makes it a valuable reference for researchers investigating the historical continuity of unexplained aerial sightings.
