April 27, 2026 is the deadline that the House Oversight Committee formally requested briefings from FBI, DOD, DOE, and NASA on UAP transparency and the missing scientists investigation. This dual deadline — covering both the broader UAP transparency inquiry AND the active federal investigation into 11+ missing and dead scientists — lands today. Context: DOD already missed the April 14 deadline for the 46 named UAP video files. The Pentagon’s mechanism for “losing” Luna’s letter has been documented. The FBI confirmed it is “spearheading” the missing scientists investigation (April 17-18, 2026 statements from Director Kash Patel). NNSA confirmed its own probe. Trump publicly stated “pretty serious stuff — I just left a meeting on that subject” when asked about the missing scientists. The White House confirmed a “holistic review” of the cases. DOD separately told Congress on April 16, 2026 that it is NOT investigating any missing persons — directly contradicting the FBI and NNSA probes. The congressional deadline creates a binary test today: do agencies provide substantive briefings, or do they again claim inability to pass letters to appropriate authorities? AARO caseload: 2,400+ reports. Five agencies requested. The April 27 date has been tracked in this intelligence operation since it was first announced. Watch this date. The agencies know what they have.
