4 August 1990 claimed photograph date; surviving print published 13 August 2022 / T169
Calvine: authentic archival connection does not identify the object
Claimed location near Calvine, Perthshire, Scotland
Witness account
Photographs allegedly taken near Calvine on 4 August 1990 showed a large diamond-shaped form with an aircraft in the scene. The material was passed through the Daily Record to the Ministry of Defence. A print retained by former RAF press officer Craig Lindsay became public on 13 August 2022, reviving a case long known principally through documentary references.
Public record
Andrew Robinson’s photographic analysis, available through Sheffield Hallam University, supports the print’s connection to the material examined by the MoD in 1990. It treats the image as a photograph of a scene, while emphasizing that its date and location cannot be derived from the print and the photographer remains unidentified.
