Codified by Hal Puthoff at TTSA and reiterated by Luis Elizondo at AATIP: the five characteristics that distinguish UAP from known aircraft.
| # | Observable | Threshold |
|---|---|---|
| 1 | Instantaneous acceleration | 2,000-3,000+ g |
| 2 | Hypersonic velocity (no signature) | 10,000+ mph |
| 3 | Low observability | Visible but indescribable shape; radar spoofing |
| 4 | Trans-medium travel | Air, water, space: no design penalty |
| 5 | Positive lift / Anti-Gravity | Sustained flight, no wings/exhaust |

The sixth observable
Imminent adds a sixth characteristic which it says “has not yet been discussed publicly by our government”: biological effects, meaning burns, organ damage, hair loss and missing time. This is the book’s framing rather than a government one, and the evidence offered for it is described rather than reproduced. See Garry Nolan for the MRI cohort it rests on and Cash-Landrum Incident 1980 for the injury case that has a public history.
