In the first article of this series, we explored Why the Pentagon Stopped Ignoring UAPs and how the taboo was broken. Now, we need to look at the data. What makes these objects so disruptive is not just their presence, but their challenging physics.
US military intelligence classified the behavior of these anomalies through the so-called “Five Observables”. These are the technical criteria that separate conventional drones from truly unknown technologies.
The Five Observables: Breaking the Laws of Physics
For an event to be taken to the AARO as a real anomaly, it must display one or more of the following characteristics:
- Anti-gravity Lift: Objects without control surfaces (wings) or visible propulsion sources (turbines) that remain static or move at high speed.
- Sudden and Instantaneous Acceleration: The ability to go from inertia to hypersonic speeds instantly, withstanding G-forces that would destroy any human aircraft.
- Hypersonic Velocities: Speeds exceeding Mach 5 without generating a sonic boom or heat signature.
- Low Observability: The ability to become invisible to radar or the human eye (active camouflage).
- Trans-medium Travel: Fluid movement between space, the atmosphere, and the ocean without a change in performance.
Sensor Fusion: Beyond Human Sight
We no longer rely solely on pilot reports. The modern era of investigation is based on Sensor Fusion. When a SPY-1 radar detects a target, infrared cameras (FLIR) track it, and satellites confirm the position, human error is ruled out.
“The technology observed in UAPs suggests a science that not only masters aerodynamics but manipulates the very fabric of space-time.”
In the next and final article of this trilogy, we will discuss the implications of this: The Intelligence Gap: National Security in the Age of Anomalies.
What separates a bird or a drone from a true anomaly? U.S. military intelligence uses the “Five Observables” to categorize objects that defy known physics.
- Instantaneous Acceleration: Moving from stop to Mach 5+ instantly.
- Trans-medium Travel: Moving between space, air, and sea without friction.
These capabilities represent a massive Intelligence Gap for global defense. To master the terminology used in these technical reports, consult our UAP Technical Glossary.
