PURSUE Corpus Analysis

The physics don't work

The PURSUE declassified records describe specific, measurable physical behaviors. When you run the numbers, the implied forces exceed every known limit by orders of magnitude. These are not edge cases. They are not rounding errors.

The 1/30th-Second Problem

A Range Fouler Debrief form from USCENTCOM, October 2020, contains the following verbatim observation. It is the single most physically extreme claim in the entire PURSUE corpus.

"ONE RANGE FOULER WAS CIRCLING AROUND THE OTHER IN 1/30TH OF A SECOND."

Off every known scale. At 1 m separation, the implied G-force is 3,622 G. The F-22 Raptor structural limit is 9G. Human consciousness loss occurs at ~5G. No known material, aircraft, or biological system survives forces of this magnitude.
How to read this: The document states one object circled another "in 1/30th of a second." The calculation requires one unknown: the distance between them. Adjust the radius above to explore different assumptions. Even at 1 meter separation—the absolute minimum plausible for two distinct objects—the implied G-force is 3,622 G. At the more realistic 10-meter separation, it is 36,222 G. There is no radius at which this is physically achievable by any known technology.

Acceleration G-Force Calculator

Multiple PURSUE reports describe objects accelerating from stationary or near-stationary to high speed with no apparent transition. Enter a speed change and time elapsed to calculate the implied G-force.

Methodology note: All calculations use standard Newtonian mechanics. G-force from circular motion: G = 4π²r / (T² × 9.81). G-force from acceleration: G = Δv / (t × 9.81). G-force from turn: G = v² / (r × 9.81). No relativistic corrections applied. Source values are taken verbatim from PURSUE declassified documents available at war.gov/ufo. Unknown parameters (such as orbital radius in the DOW-UAP-D58 observation) are adjustable in the calculators above.
