AARO Eglin case resolution: moderate-confidence lighter-than-air object, not anomalous craft

AARO's UAP Case Resolution Reports page lists Eglin Case Resolution with a short synopsis: a military pilot reported the object due to its potential as a flight safety hazard and an incursion into a sensitive training range.

The primary product is AARO's Case: Eglin UAP case-resolution report dated October 14, 2023. Location is near Eglin Air Force Base, Florida. Date is January 26, 2023. Reported altitude for the visually observed object is 16,000 feet. Sensors listed are electro-optical, infrared, visual identification, and radar.

Case status on the product: Resolved; very likely a lighter-than-air object, such as a large commercial lighting balloon. Confidence level: Moderate. Behavior line: No confirmed anomalous behavior.

Through onboard radar, the pilot initially observed four objects aloft between about 16,000 and 18,000 feet that appeared to be flying in formation. The pilot observed only one of the four objects visually and captured two still images of that single object with the aircraft EO/IR sensor.

Aircraft video recording equipment was inoperable before and during the flight, so AARO's public product is built from still imagery, the pilot report, a later AARO discussion with the pilot, and reconstruction work rather than a full video case file.

The pilot described the object as gray with a paneled surface and orange-red coloring at the center. Later discussion added an estimated diameter of about 12 feet and motion that was either very slow or potentially stationary. The bottom half was described as rounded and the top as a rounded three-dimensional cone, compared by the pilot to an Apollo spacecraft shape.

The pilot also described blurry air under the rounded bottom, interpreted as a heat signature. In the later AARO discussion, the pilot said they thought they saw a vertically oriented engine on the side nearly the height of the object. That feature is not visible in the two still images and was not in the initial report. AARO says it has no additional data to corroborate an engine.

There was no EO/IR data for the other three radar contacts, so AARO could not analyze those reported objects.

AARO assesses the reported UAP very likely was an ordinary object and was not exhibiting anomalous or exceptional characteristics or flight behaviors. AARO states moderate confidence in that overall assessment because of limited data.

AARO assesses the object was a lighter-than-air object such as a large form-factor balloon, a meteorological balloon, a large Mylar balloon, or a large commercial outdoor helium-filled lighting balloon. Confidence on that object identification is also moderate.

AARO submitted the case to an Intelligence Community partner and a science and technology partner. Both independently reached high-confidence assessments that the object did not exhibit anomalous characteristics or behaviors and very likely was some form of balloon.

Lead citation lines: moderate confidence AARO lighter-than-air identification, high-confidence partner assessments of ordinary balloon-class object and no anomalous behavior, no confirmed anomalous flight characteristics.

AARO based the assessment on review of collected data, official pilot accounts, laboratory testing of a commercial lighting balloon with similar physical characteristics, reconstruction of flight geometry, and sun angle at the time of observation.

AARO identified a commercial lighting balloon as a close visual match to the zoomed-in infrared image. Some models have distinct black and white hemispheres, with the upper hemisphere lined to direct light downward. Testing found the balloon could replicate some aspects of the pilot account, including panel-like seams that can read as ribbed fabric.

AARO notes the orange-red center could be sun glint or, in partner analysis, red-colored tether points on larger balloons. The blurry-air observation could be environmental misperception, a tether hanging below, or motion-induced image blur.

Beyond lighting balloons, AARO says the description also correlates with any large-form balloon made of two materials or colors with different infrared properties. Sun angle and sensor look angle can illuminate the bottom half while the top appears dark and cold.

The pilot reported that upon closing to within about 4,000 feet of the object, the aircraft radar malfunctioned and stayed disabled for the remainder of the training exercise.

Post-mission review found a circuit breaker had tripped. Technicians reported the same breaker on that aircraft had tripped three times in prior months and could not conclusively diagnose the cause for this incident.

Based on that prior history, AARO assesses the malfunction likely was not caused by or associated with the object. No anomalous flight characteristics, behaviors, or capabilities were confirmed.

That matters for citation. A dramatic radar dropout near a range contact is not, in AARO's product, evidence of directed-energy effects or exotic interference. It is treated as a pre-existing aircraft fault coinciding with the event.

AARO could not analyze the other three radar contacts because there was no EO/IR data for them. The resolution applies to the visually observed and imaged object.

Moderate confidence is not the same as high-confidence closed identification on every detail. AARO is explicit that limited data cap confidence even while partner reviews land high confidence on no anomalous behavior.

Eglin does not resolve Gimbal, FLIR, GoFast, mother-orb products, or every training-range report. Those remain separate source trails.

Safe citation: Eglin is a resolved public case where a January 2023 Eglin-range pilot report was assessed as a very likely ordinary lighter-than-air object with moderate confidence, partner high-confidence ordinary/balloon findings, and no confirmed anomalous behavior. Unsafe upgrade: treating the pilot's engine impression or radar dropout as proven exotic effects, or using the balloon finding to close every open UAP case.

Cite the confidence split exactly: AARO moderate confidence on ordinary/LTA identification because data were limited; IC and S&T partners high confidence that the object was not anomalous and very likely a balloon.
