The Five Observables
The Five Observables are a framework used to describe unusual flight characteristics reported in hundreds (if not thousands) of UAP cases since at least WWII.
These observables are often discussed in connection with The United States Department of Defence (DoD), The 2017 New York Times article revealing the Pentagon’s UAP program AATIP (Advanced Aerospace Threat Identification Program) and the UAP videos such as the “Tic Tac” encountered by U.S. Navy pilots including David Fravor (“The Black Aces”), who testified before the United States Congress on July 26, 2023.
The term was first introduced to the general public by Luis Lue Elizondo and is detailed in his publication Imminent (2024). Lue previously led AATIP.
The Five Observables are categories of observed performance characteristics that clearly exceed human conventional aerospace technologies. They are proof that Non-Human Intelligence (NHI) is and has been monitoring human activities and life on Earth.
The first Observable is hypersonic velocity:
Sound travels at a speed of 762 miles/hr. Hypersonic means Mach 5, five times the speed of sound (about 3,800 to 4,000 miles/hr).
Why these UAP sightings are unusual and currently still unexplained by our ‘modern’ understanding of physics?
Our best military equipment can detect that these UAP accelerate extremely rapidly without visible propulsion, reaching speed of up to Mach 17 (>13,000 miles/hr and at low altitude), often going from hover to hypersonic speeds in seconds, without any sonic boom, no signature, no heat ablation or atmospheric ionisation.
Human made aircraft and technology require gradual acceleration due to inertia and major structural limits.
Observable #2 - instantaneous acceleration:
The UAP we are observing can sometimes travel even faster than Mach 17, and can stop on a dime, including high speed right-angle turns at speeds up to ten times faster than the SR-71 (the Blackbird), generating several thousand g-force.
Why it’s unusual?
Conventional physics predicts shockwaves at such speeds, and any current human-made technology would be shredded into pieces with such g-force. Pilots black out around 9 -12 g (with suits). Also, delivering this amount of energy in seconds requires power outputs comparable to large power plants or even more (some argue the entire daily power supply of the US), without visible propulsion.
Observable #3: Low Observability
UAPs often:
Appear invisible to radar but visible to the eye,
Appear visible on infrared but not visually,
Are difficult to track consistently across military sensors,
Capturing clear data is apparently still very challenging,
No observable signature, no sonic booms, no sound...
Why it’s unusual?
Our modern stealth reduces radar return but does not eliminate multi-sensor detection so inconsistently. All human modern technologies have a signature (acoustic, electronic, environmental, thermal or visual).
To selectively appear or disappear across X-band radar, infrared or visible light, you would need active electromagnetic field manipulation or plasma cloaking.
Observable #4 – Trans medium Travel:
Observed UAPs have the capacity to operate and move in multiple environments (including between our atmosphere, our oceans and space) without compromising their performance, without slowing down or changing apparent configuration.
Why it’s unusual?
For example air-to-underwater transition at high speed should create extreme drag and structural stress. To avoid this, we would need a field that displaces water before contact or extreme structural strength beyond known alloys.
Observable #5 - Positive Lift / Antigravity:
These UAPs can hover or manoeuvre without wings, without rotors and without exhaust plumes, defy the natural effects of Earth’s gravitational pull, without any obvious signs of propulsion or lift, no control surfaces.
Why it’s unusual?
Conventional flight requires aerodynamic lift or thrust vectoring.
To conclude, the Five Observables reflect reports from trained observers and multi-sensor systems. All five observables challenge conservation of momentum, conservation of energy, fluid dynamics (compressible flow), material strength limits and human survivability constraints.
The Exotic Propulsion Hypothesis requires space-time metric engineering (Alcubierre-like warp concepts), inertia modification, field propulsion and breakthrough energy generation.
