📡 Daily UAP News Digest — 2026-04-29 Curated, organized, and formatted by AI, focusing on authoritative sources and major developments.

US Government Disclosure Updates

On April 28, the US House Oversight and Accountability Committee held a UAP hearing where former DoD UAP task force lead Sean Cahill testified that a ‘secret program’ within the Pentagon has been recovering and reverse-engineering vehicles of non-human origin. Cahill said the program is controlled by senior DoD officials and even the AARO director lacks full access. Several lawmakers demanded the release of AARO’s fiscal 2025 annual report and criticized the military for ‘systematic lack of transparency’ in sharing UAP information.

International UAP Incidents

On April 29, the Brazilian Navy released an infrared video captured by a patrol aircraft over the Amazon rainforest, showing multiple unidentified objects performing erratic maneuvers at extremely high speeds with no visible engines or heat signatures. The video was recorded in December 2025 by a P-3 Orion aircraft over northern Brazil but was declassified only this week. The Navy stated the objects appeared repeatedly on both radar and optical sensors, exceeding known aircraft capabilities, and the case has been transferred to the Joint Space Command for investigation.

Japan Establishes UAP Investigation Unit

On April 28, Japan’s Ministry of Defense officially announced the establishment of the ‘UAP Countermeasures Office’ to collect and analyze UAP reports from Japan Air Self-Defense Force pilots. The unit will integrate radar data, pilot testimony, and meteorological information, and plans to share data with the US military and JAXA. The Defense Minister stated at a press conference that the number of UAP reports received by the JASDF has increased significantly in recent years, with 47 cases in 2025 compared to just 8 in 2020.

New Scientific Research

The Astrophysical Journal published a study on April 28 by researchers from Harvard University and Caltech, analyzing over 2,000 UAP reports from the US Navy between 2015 and 2023. Using a machine learning model, the team found that about 15% of the reports described object trajectories inconsistent with known atmospheric or physical models, and these anomalous events often occurred near military exercise zones. Co-author Avi Loeb, chair of Harvard’s astronomy department, said the data ‘cannot be fully explained by natural phenomena or sensor errors.’
