The Pentagon has released a seventh series of declassified files on unidentified flying objects. The batch includes a report on a mysterious black object, one of the sightings recorded in the historical material. The releases form part of an effort to open long-sealed records to public view, file by file. Decades of collected reports sit in the archive, logged with whatever detail witnesses and instruments provided at the time. Public hearings in Washington pushed the subject back into mainstream debate in recent years. Interest has stayed high enough that each new batch draws attention on its release. Few entries in the files close with firm conclusions, and the black object case is no exception. The seventh instalment implies more batches remain in the pipeline as reviews wrap up.
