The Melbourne flight-service ATC audio from 21 October 1978: Valentich's own voice on tape, the metallic noise that ended the transmission, and the 30 seconds the operator kept calling before declaring the aircraft missing.
The Melbourne Flight Service Centre tape of Valentich's final transmission is the primary audio record of his disappearance. The aircraft's last position was near Cape Otway, Victoria, headed for King Island. The audio captures Valentich's own voice describing an object pacing him, the metallic sound that ended the transmission, and the Flight Service Officer's standard 30-second hold before declaring the aircraft missing.

Produced by the Defence Intelligence Staff's DI55 branch between 1997 and 2000, Project Condign is a 400-page analytical study of unidentified aerial phenomena in the UK air defence region.

Part 05 sits in the middle of the LAC FOIA release. The institutional ledger by this point is dense with running correspondence, incident report forms, and inter-agency referrals.

On 8 January 1981 around 17:00, Monsieur Colini observed an unidentified craft descend between two large conifers onto the terrace of his Trans-en-Provence property in the Var, rest for an estimated 30-40 seconds, and depart rapidly to the northeast at between 30 and 70 meters from him throughout. Gendarmerie arrived the next morning, photographed the site, auditioned the witness, and forwarded soil and plant samples to INRA laboratories. The TN 16 dossier integrates witness testimony, gendarmerie records, and the multi-lab forensic findings (soil compaction consistent with mechanical loading, iron and phosphate traces, sub-600 C thermal indicators, distance-graded biochemical changes in alfalfa specimens). The agency's stated threshold for opening a formal inquiry was that two independent evidence types had to be present and confrontable; Trans-en-Provence cleared that bar.
