UAP (Unidentified Aerial Phenomena)

A term used by the U.S. government to describe airborne objects that defy conventional explanation, often exhibiting flight characteristics beyond known human technology.

One or more of the Five Observables are the hallmarks of the most interesting UAP encounters. These were popularized by the U.S. Navy and researchers such as those involved with AATIP (Advanced Aerospace Threat Identification Program):

• Sudden and instantaneous acceleration
  (Extreme speed changes that defy known propulsion limits and inertial tolerances)
  — Cmdr. David Fravor described a “Tic Tac”-shaped object during the 2004 Nimitz encounter that dropped from 80,000 feet to sea level in under a second. This maneuver was tracked by radar and visually confirmed.
• Hypersonic velocities without signatures
  (Traveling at speeds exceeding Mach 5 with no visible exhaust, sonic booms, or heat plumes)
  — The USS Princeton’s SPY-1 radar tracked multiple UAPs performing hypersonic maneuvers. In the declassified “GoFast” video (2015), an object is seen skimming above the ocean at high speed with no thermal plume or visible means of propulsion.
• Low observability
  (Stealth features such as radar evasion, transponder silence, and visual cloaking)
  — Pilot Ryan Graves testified that objects would appear on radar and IR sensors but not visually—suggesting selective observability. In the declassified “Gimbal” video (2015), the object maintains a stable heat signature while rotating, with no visible wings or exhaust, and demonstrates anomalous radar cross-section behavior.
• Transmedium travel
  (Seamless movement between air, sea, and space without loss of performance or structural damage)
  — Sonar operators and pilots from multiple Navy incidents have described craft entering or exiting the ocean at high velocity with no splash or cavitation. Though not in public footage, this behavior was reported in AATIP-related case studies and aligns with statements from intelligence personnel describing “fast movers” tracked underwater at impossible speeds.
• Positive lift with no aerodynamic control surfaces
  (Ability to hover, maneuver, or maintain altitude without wings, rotors, or identifiable propulsion)
  — In the declassified “Gimbal” video, the object is observed flying against strong winds without visible lift mechanisms. The 2004 Nimitz “Tic Tac” was seen hovering motionless, then performing sharp angle maneuvers without banking, suggesting control via non-aerodynamic means—possibly field-based propulsion.
