My grandfather passed away in 2008 but before he died he told me he was serving at RAF Bentwaters during the Rendlesham Forest incident in December 1980. He wasn't involved in the actual event but he said the security lockdown afterwards was genuine - not a hoax, not mass hysteria. The base went into genuine emergency protocols for about 72 hours.
He was quite clear: something happened that the military took very seriously. He couldn't talk about specifics due to his service commitment but he implied it wasn't something the official explanations covered. Worth anything? Or just family stories?
