On the Vela Incident, and what we still do not know
Cold Light Memoranda — 15 March 2026
The Vela Incident has been the subject of more speculation than almost any other event in Cold Light's catalogue. A double flash over the South Atlantic on 22 September 1979. A possible nuclear test. A possible meteor. A possible instrumentation error on the Vela 6911 satellite.
The declassified record is clear on what happened, less clear on what it means. The Carter administration concluded internally that a nuclear test was "more likely than not." The 1980 DARPA panel found the evidence inconclusive. The 2010 NRL review suggested a meteoroid strike on the satellite itself.
What is not in dispute: the flash occurred. The satellite recorded it. Multiple sensors corroborated it. What remains disputed is the interpretation.
Episode 001 presents all three interpretations without resolving them. This is not evasion. It is accuracy. The file does not resolve, and we do not pretend that it does.
The next episode, on Operation Mockingbird, is in final fact-check. We expect publication on 1 April.
