I've been following the Rendlesham incident for decades (like many of you, I'm sure), and I just received a batch of previously unreleased documents through the National Archives' latest digital dump. Most of it's old hat, but there's one memo from RAF Bentwaters commander that's absolutely damning.
The memo, dated 27 December 1980, discusses a 'decision to class the incident as unexplained military exercises' rather than the more incriminating 'craft of unknown origin' determination from the initial reports. The language is carefully diplomatic, but it's essentially admitting they changed the official classification to something less alarming.
Why would they swap from one cover story to another? If they'd been running exercises, that would be the natural explanation from the start. Instead, we get the exercises story after the incident, almost like they needed time to construct a narrative that would hold up.
I've attached high-res scans of the key pages. The handwriting on one is particularly interesting - looks rushed, possibly written under pressure. Thoughts?
