National-security witness · Immaculate Constellation
Matthew Brown
Brown says he encountered material suggesting a compartmented system for gathering and controlling UAP-related intelligence. In his account, the significance is not only alleged anomalous craft but the possibility that information is collected and sequestered without adequate oversight. The programme’s name appears in a document submitted for the November 2024 House hearing. Its presence in a congressional submission proves the allegation was presented, not that the programme exists.
