On November 13, 2024, journalist Michael Shellenberger published a report attributed to an anonymous Pentagon source describing an alleged Special Access Program code-named 'Immaculate Constellation' purportedly tracking and recovering UAP.

The report was submitted to Congress and discussed at the same-day House Oversight hearing, but the underlying SAP has never been verified by any agency, named witness, or independent record. The Pentagon publicly denied knowledge. This entry exists for context, anonymous whistleblower material is not government disclosure.
