Editing Calvine Photo Incident — Key Persons Directory (section)

=== Researchers and Analysts ===

==== Dr David Clarke ====
[[David Clarke (Doctor)|Dr David Clarke]]Associate Professor, Sheffield Hallam University; journalist; folklore researcher; former MoD UFO files consultant. Identified Craig Lindsay through FOI research in 2021; conducted the investigation that led to the photograph's public release in 2022; continues to investigate the witness identity question. His work on the Calvine case is the most substantive investigative contribution to any UK UFO case in recent decades.

==== Andrew Robinson ====
[[Andrew Robinson]] - Photography specialist and lecturer, Sheffield Hallam University. Conducted the detailed photographic analysis of the original Craig Lindsay print. His conclusion: the photograph is genuine; the image is the same as the 1990 photocopy faxed to the MoD and the Vu-Foil copies in the National Archives. His 34-page analysis report (updated 2024) is the definitive technical assessment of the surviving photograph.

==== The DI55 Source ====
An unnamed Defence Intelligence Officer whose claim to Clarke — that the Calvine object was a US classified platform from RAF Machrihanish — triggered the renewed investigation in 2018. This source's identity has not been publicly disclosed. Their claim remains the most specific inside account of what the MoD believed the photographs showed.
