Open research question
Trace the earliest surviving documentary source for each major Rendlesham Forest claim, including the initial forest observations, physical traces, radiation measurements, radar-related claims, audio recording, witness statements and Halt memorandum.
A source, research note, or further-reading link closes this question when staff accept it. Evidence and corrections stay attached for staff and do not close it by themselves.
Staff review every contribution before it is added to the file. A correction is a proposal: accepting it does not replace the official record. Rejected items are handled like rejected case submissions.
