GoFast Incident (ATFLIR, 2015) — 5-Observables Gap Analysis

AeriTrax analysis

The released 35-second ATFLIR clip shows a small object tracked low over water at apparent high speed. The release preserves the sensor track and pilot commentary but omits the observer-velocity, range-rate, and atmospheric reference data needed to distinguish actual object speed from parallax. Independent analysts have argued the apparent speed is partially a parallax artifact; the released data is insufficient to settle the question either way.

Scoreboard

0 Evaluable
1 Partial
4 Cannot evaluate

This release supports evaluation of 0 of 5 observables in the Pentagon framework.

Per-observable analysis

OBSERVABLE 1

Sudden / instantaneous acceleration

Cannot evaluate
Required to evaluate
Calibrated linear acceleration of the object derived from observer GPS-velocity, range-rate, and a per-frame bearing reference.
Released data
Sensor angular position and elevation rate are visible in the ATFLIR overlay. Observer aircraft GPS velocity in machine-readable form and continuous range-rate to the target are not included.
AeriTrax live capture would have provided
For a ground witness in the same scene, AeriTrax records a per-frame sensor stream at ~50 Hz with magnetometer-derived bearing plus accelerometer angular rate. The witness's stationary frame eliminates the observer-velocity-induced parallax that complicates the F/A-18 platform's track.
OBSERVABLE 2

Hypersonic velocity without signature

Cannot evaluate
Required to evaluate
Synchronized ambient audio at the observer plus an independent observer-velocity estimate.
Released data
Audio is intra-cockpit voice. No external microphone track. No external ambient acoustic baseline.
AeriTrax live capture would have provided
Device microphone recording correlated with capture timestamps, enabling absence-of-acoustic-signature claims to rest on recorded negative evidence.
OBSERVABLE 3

Low observability

Partial data
Required to evaluate
Continuous frame coverage at known fps plus a per-capture sensor-blink and gap log.
Released data
The 35-second clip is continuous at the ATFLIR's standard frame rate. There is no per-frame sensor-blink ledger that would distinguish 'object exited the field of view' from 'object stopped being detectable.'
AeriTrax live capture would have provided
Per-capture frame-timestamp ledger that distinguishes sensor failure from subject disappearance, plus AR-overlay subject track.
OBSERVABLE 4

Trans-medium travel

Cannot evaluate
Required to evaluate
Pre-event and post-event imaging of the water surface or atmospheric-layer transition zones in the object's track.
Released data
The water surface is visible in the ATFLIR field of view throughout the clip, but the IR sensor mode and resolution are insufficient to evaluate water-surface interaction. No before/after imaging is preserved.
AeriTrax live capture would have provided
Pre-burst water-presence classification via on-device coastline polygons; the AR overlay's timeline would anchor the object's altitude trace against the local water surface.
OBSERVABLE 5

Positive lift / propulsion without surface

Cannot evaluate
Required to evaluate
Thermal-IR signature delta over time plus acoustic data sufficient to evaluate propulsion-method consistency.
Released data
ATFLIR IR preserves only the object's bulk signature track, not per-component thermal evolution. No acoustic data.
AeriTrax live capture would have provided
Thermal-context flags via the AR-overlay's sensor stream and acoustic capture from the burst-window microphone — both inputs needed to support or rule out propulsion-method inferences.

What the release contains

The GoFast clip is 35 seconds of ATFLIR video from a US Navy F/A-18F Super Hornet, recorded during the same January 2015 USS Theodore Roosevelt operating period as the Gimbal clip and the broader 2014–2015 East Coast Carrier Strike Group encounters. Sensor-track markings are visible: range (~3.3 nautical miles initially), azimuth, elevation rate, sensor mode. Audio is intra-cockpit pilot reaction.

The Department of Defense authenticated the clip in April 2020, following the December 2017 To The Stars Academy release. It is part of the three “official” DoD-authenticated US Navy UAP clips alongside FLIR1 (Tic Tac) and Gimbal.

What the release does not contain

The release is the sensor feed plus audio. Missing for evaluation:

  • Observer aircraft GPS velocity. The apparent speed of the object — the headline framing of the clip — depends critically on separating the F/A-18’s own motion from the object’s motion. The release does not include a machine-readable observer-velocity trace synchronized to the frame timeline.
  • Continuous range-rate. ATFLIR initial range is visible (~3.3 NM) but a continuous range-rate signal across the full clip is not preserved. Independent analysts have argued the apparent speed is partially parallax (sensor-line-of-sight rotation rate rather than object ground speed); the released data is insufficient to settle this either way.
  • Sea state and surface temperature. The water surface visible in the IR field is the parallax reference for the object’s apparent path. Sea state, surface temperature, and wave-direction context are not included.
  • External audio. Ambient acoustic conditions at the F/A-18 external sensor (or at any independent ground observer) are not preserved.
  • Companion sensor data. Whether the F/A-18’s radar held a return on the same object at the same range-rate is not in the public release.

What an AeriTrax live capture at a ground witness would have added

AeriTrax is a ground-observer instrument. A credible ground witness in the same airspace would have produced a parallel data trace from a stationary frame, eliminating the observer-velocity-induced parallax question that complicates the GoFast track in particular.

The gap report above lists what AeriTrax would have captured per observable. In aggregate: bearing-stamped sensor stream, ambient audio, frame-timestamp ledger, calibration state, GPS-fix accuracy, ADS-B traffic correlation, satellite-pass cross-reference, all anchored to a signed manifest. The ground witness would not produce a thermal-IR track, but the elimination chain (ADS-B / ephemeris / Remote ID / weather context) applied to the same window would either match the object to a conventional explanation or surface the residual the ATFLIR feed alone cannot.

The release is sufficient to establish that the F/A-18’s sensor recorded an object on a track that looks fast in cockpit view. It is not sufficient to evaluate the Pentagon-framework velocity claim, or any of the other observables, in isolation.
