GoFast: The 2015 Navy Video and AARO Analysis

Evidence Dossier: A record proves that a statement, transfer, examination, or result was documented. It does not automatically prove the anomalous interpretation attached to it.

Atlantic Ocean east of Florida, USA

A Navy infrared video captured an unidentified object traveling at extraordinary speed just above the ocean.
Strong for the existence and official provenance of the video and for AARO’s published calculations; limited for exact speed, heading, position, and object identity because the analysis lacked complete aircraft track and atmospheric data.

Investigative Assessments

"The reported claim remains worth testing against the record: A Navy infrared video captured an unidentified object traveling at extraordinary speed just above the ocean. The strongest documented reasons to keep the file open are: AARO GoFast Case Resolution Report: AARO assessed the target at about 13,000 feet and modeled a wind-compensated speed range of about 5 to 92 mph, with high confidence that it showed no anomalous performance; AARO Open-Hearing GoFast Slide: The slide states that the target was assessed at about 13,000 feet and about 45 mph, while winds at that altitude were about 60 knots. Key unresolved lead: What was the recorded object?"
"Evidentiary limitations: Strong for the existence and official provenance of the video and for AARO’s published calculations; limited for exact speed, heading, position, and object identity because the analysis lacked complete aircraft track and atmospheric data. Note that: AARO GoFast Case Resolution Report fails to support: The report does not identify the object and warns that incomplete track and atmospheric data prevent an exact position, heading, or speed solution; AARO Open-Hearing GoFast Slide fails to support: A summary slide does not expose the full computational model, and its statement that DoD released the video in 2017 conflicts with the 2020 date in the detailed report. Documented contradiction: The target appeared to be moving rapidly near the ocean surface, but AARO calculated an altitude of about 13,000 feet. Leading conventional hypothesis: Parallax amplified apparent motion as the fast aircraft viewed a distant target against the surface."

Case Summary

A source-level review of the Navy GoFast video and AARO’s later computational analysis. The object is real as a recorded sensor target, but the available records do not establish exceptional speed, low-altitude flight, or extraterrestrial origin. AARO could not identify the object and assessed with high confidence that it showed no anomalous performance.

AARO Parallax Information Paper

Analyst rating: Strong for the general optical mechanism, but not an independent reconstruction of GoFast

“Because of parallax, stationary objects can appear to have motion, and slow-moving objects can appear to move very fast.”

Evidence classGovernment technical-methods record
Relationship to claimProvides the optical mechanism used in the case-specific report and states its scope and limits.
Authenticity assessmentHigh for document authenticity. The relevant page was visually checked against the NARA PDF.
What this supportsThe paper explains how a moving airborne observer can make a stationary or slow object appear to move rapidly against a distant background.
What it does not supportA general methods paper does not prove that parallax completely accounts for this specific target.

Documented Timeline

  • 2015-01: A Navy F/A-18F recorded the target using a forward-looking infrared sensor east of Florida.
  • 2017: The video became publicly known; an AARO hearing slide later described this as a DoD release, while the detailed report states the official DoD release occurred in 2020.
  • 2020: DoD officially released the GoFast video, according to AARO’s detailed case report.
  • 2024-05: AARO produced a general information paper on forced perspective and parallax.
  • 2025-02-05: AARO presented a GoFast summary to the Senate Armed Services Subcommittee on Emerging Threats and Capabilities.
  • 2025-02-06: AARO dated its detailed GoFast case resolution report.

Named Participants and Roles

  • Unidentified U.S. Navy F/A-18F pilot and aircrew: operators associated with the January 2015 recording.
  • Unidentified AARO and science-and-technology analysts: authors of the reconstruction and parallax analysis.
  • Dr. Jon Kosloski: AARO director named on the 2025 hearing-slide deck.

Contradictions and Record Conflicts

  • The target appeared to be moving rapidly near the ocean surface, but AARO calculated an altitude of about 13,000 feet.
  • The visual impression suggested exceptional speed; AARO’s modeled wind-compensated range was about 5 to 92 mph.
  • The hearing slide says the video was released by DoD in 2017, while the detailed report says DoD officially released it in 2020.

Conventional Explanations

  • Parallax amplified apparent motion as the fast aircraft viewed a distant target against the surface.
  • A balloon or other lightweight wind-influenced object is compatible with part of AARO’s modeled range, although AARO did not identify the object.
  • A conventional airborne object traveling within the modeled range would not require anomalous propulsion.

Evidence Stance Matrix

Not documented: No explicit evidence stance matrix has been reviewed.

Missing Evidence

  • The complete original sensor data and uncompressed recording are not included in the acquired NARA set.
  • The aircraft’s true-track latitude and longitude were not provided to AARO.
  • Exact atmospheric conditions and a definitive object identification remain absent.

What Remains Unresolved

  • The target remains unidentified despite AARO’s nonanomalous-performance assessment.
  • The true speed and heading can only be bounded across assumed wind and aircraft paths.
  • AARO’s altitude calculation is described as high confidence, but the target’s physical nature is unresolved.

Investigative Hypotheses

  • A lightweight object moving generally with the wind appeared faster because of parallax
  • A conventional aircraft or other object followed a nonanomalous trajectory within AARO’s modeled range
  • The target had exceptional performance that was obscured by incomplete data, although the acquired official analysis does not support that interpretation

Open Questions

  • What was the recorded object?
  • What would the original sensor file and full aircraft telemetry change about the speed and heading bounds?
  • Why does one official slide say the video was released by DoD in 2017 while the case report says DoD officially released it in 2020?
