This hit the news yesterday and I thought it relevant to share here. The National Archives released a memo (ref: AIR 2/17123) from an RAF Wing Commander dated December 28th, 1981, three days after the main Rendlesham Forest incident.
The memo is heavily redacted, but what's visible is interesting. Reference to 'unidentified luminous phenomenon' and a note about 'trajectory inconsistent with known aircraft.' There's also a line that's been almost completely blacked out, but the word 'radioactive' appears to be underneath.
The document confirms what we've suspected: the military took this seriously. Whatever was in Rendlesham Forest wasn't dismissed as swamp gas or a lighthouse. I've attached the PDF and a higher-contrast version. Have a read and let me know what you think.
