These slides from the Department of Defense's All-Domain Anomaly Resolution Office (AARO) accompanied testimony by Director Dr. Jon Kosloski to the Senate Armed Services Subcommittee on Emerging Threats and Capabilities. They were reviewed and released in full in February 2025. They chart UAP reporting trends from 1996 to 2024, showing that most closed cases were resolved as balloons. They also present analyses finding that the 2013 Puerto Rico object, the 2015 GO FAST video and the 2018 Mt. Etna object showed no anomalous flight characteristics.

THE PUERTO RICO OBJECT
▪ Analytic Factors: Perception of objects’
fading in and out due to Thermal
Crossover.
▪ Trajectory reconstruction shows the
objects traveled southwest in a straight
line at a consistent speed of ≈3.6
meters per second while slowly
descending to ≈200 meters.
▪ Winds were 7 knots (3.6 m/s) out of the
east-northeast. Cloud cover was
approximately 50 percent, with scattered
clouds at 914 meters (3000 feet).
Vector analysis is used to plot the line of sight of the sensor as a function of time. Using a closest-approach
method, a track of the object can be estimated
