After fourteen months of waiting (submitted May 2023, got it last week), I finally received a response to my Freedom of Information Act request. I'd asked the Ministry of Defence to release any files relating to 'unidentified aerial phenomena observations' from Porton Down during the late 1970s and early 80s.
Here's the thing: they released 127 pages. But 43 of those pages are redacted. Not lightly redacted - completely blacked out. "National security" reasons, apparently. What I can read is genuinely interesting though. There are incident logs from 1978 describing observations of 'anomalous objects' detected on radar in the Wiltshire area, with notes like "speed inconsistent with known aircraft" and "no identification after three-hour observation period."
The frustrating bit is that the redacted sections seem to be the actual analysis and conclusions. We've got all the 'what happened' but none of the 'what did we think about it.' I'm wondering if anyone here has experience appealing FOIA redactions? Or if anyone's got documents from the same period they could cross-reference with?
