Introduction

A central finding of the All-domain Anomaly Resolution Office (AARO) is that many reports initially classified as unidentified become identifiable once investigators obtain better context. Rather than relying on a single photograph or witness account, AARO combines radar data, infrared imagery, flight information, satellite records, environmental conditions and additional sensor data to determine whether an object was a balloon, bird, drone, aircraft or another ordinary phenomenon. The office’s published reports show that this process has steadily reduced the number of unexplained cases without producing evidence of extraterrestrial technology. At the same time, AARO emphasises that some reports remain unresolved because the available data are incomplete, not because they have been shown to involve non-human craft.

The resolved case pattern in AARO reporting

The strongest evidence for AARO’s approach comes from its published statistics rather than from a handful of famous incidents.

The Fiscal Year 2024 consolidated report states that AARO resolved 118 cases during the reporting period, with every one attributed to ordinary objects such as balloons, birds and unmanned aerial systems (drones). An additional 174 cases awaiting final administrative closure were likewise resolved as balloons, birds, drones, satellites or conventional aircraft before publication. None of these resolved investigations pointed towards exotic propulsion, unknown technology or extraterrestrial activity.

This reflects a recurring investigative pattern:

  • An object initially appears unusual because only limited information is available.
  • Investigators obtain additional sensor recordings, flight data or environmental information.
  • The object’s apparent speed, size or manoeuvres are recalculated.
  • A conventional explanation becomes consistent with all available evidence.

Rather than treating every unexplained report as extraordinary, AARO treats “unidentified” as a temporary category that often changes once enough contextual information is collected.

Why infrared video can make ordinary objects look extraordinary

Many widely discussed UAP recordings come from infrared (IR) cameras carried by military aircraft. These systems are designed to detect heat, not to provide intuitive visual images.

Several factors can make familiar objects appear mysterious:

  • Lack of distance information. A small nearby bird can resemble a much larger distant object if range is unknown.
  • Narrow field of view. Zoomed infrared sensors remove visual landmarks, making speed and direction difficult to judge.
  • Aircraft motion. A moving camera platform can create the illusion that the target is accelerating or changing direction dramatically.
  • Automatic tracking systems. Sensor software continually adjusts focus and viewing angle, sometimes creating apparent movements that originate from the camera rather than the target.
  • Thermal contrast. Infrared displays represent heat differences rather than visible colours or shapes, causing balloons, birds and drones to appear as indistinct bright objects.

These effects do not mean that every infrared recording has a mundane explanation. Instead, they explain why experienced analysts avoid drawing conclusions from a video alone and instead reconstruct the complete geometry of the encounter using multiple data sources. NASA’s independent UAP study similarly concluded that poor-quality data frequently prevent reliable identification and recommended better calibrated observations rather than speculative interpretation.

Why balloons, birds and drones are frequent solutions

The most common explanations share one characteristic: they are abundant in the same airspace where many observations occur.

Balloons

Weather balloons, research balloons and commercial balloons can drift at varying altitudes, reflecting sunlight in unusual ways or presenting unusual thermal signatures. Without accurate wind data or range estimates, their movement may appear erratic even when they are simply following atmospheric currents.

Birds

Large birds can produce unexpected radar returns, particularly when flying near military training areas or coastlines. In infrared imagery they often appear as bright, featureless objects whose flapping motion is not always obvious, especially at long distances or low frame rates.

Drones

Commercial and military unmanned aerial systems have become increasingly common. Their size, lighting, hovering capability and irregular flight paths mean they can initially resemble unfamiliar aircraft, particularly during night operations or when observed without supporting radar information. AARO therefore treats drones as one of the routine possibilities that must be eliminated before considering rarer explanations.

How additional context changes an investigation

AARO’s reports repeatedly stress that identification depends on combining independent sources of evidence.

Analysts may compare:

  • military radar tracks;
  • infrared and electro-optical camera footage;
  • aircraft flight plans;
  • satellite catalogues;
  • air traffic records;
  • weather observations;
  • astronomical information;
  • known balloon launches; and
  • intelligence reporting on drone activity.

A single witness or sensor may leave an object unidentified, while the combination of several datasets can reveal an ordinary explanation. This explains why some reports remain unresolved for months or years before eventually being closed.

What prosaic explanations can—and cannot—prove

Resolving hundreds of reports as balloons, birds or drones does not prove that every UAP report has a conventional explanation.

AARO explicitly distinguishes between resolved, unresolved and anomalous-looking cases. An unresolved case simply lacks sufficient evidence for a confident identification. It is not treated as evidence for extraterrestrial technology, nor is it automatically dismissed as a misidentification. According to the office, over 900 reports remained in an active archive because they lacked timely, actionable sensor data, allowing investigations to resume if new information becomes available.

Likewise, the existence of a small number of cases requiring further analysis does not overturn the pattern seen in resolved investigations. AARO has stated that none of its resolved cases demonstrated breakthrough aerospace capabilities or provided verifiable evidence of extraterrestrial beings, activity or technology.

Why this matters for interpreting UFO claims

Within the broader discussion of UFOs—including high-profile claims made by celebrities, pilots or public figures—the AARO record offers an important lesson about evidence. Initial impressions, even from trained observers, can change substantially once analysts reconstruct the full observational context.

The published record therefore suggests a consistent investigative outcome: many apparently extraordinary sightings become ordinary once analysts understand the object’s true distance, motion, sensor characteristics and operating environment. That pattern neither disproves the possibility of future genuinely anomalous discoveries nor confirms extraordinary claims. Instead, it demonstrates that rigorous multi-source analysis has repeatedly transformed apparent mysteries into identifiable balloons, birds, drones, satellites and conventional aircraft.
