(U) Key Findings (U) AARO assesses that the UAPs in this case were almost certainly commercial aircraft travelling on well-established aircraft corridors as far as 300 nautical miles from the platform, based on a thorough review of the data by multiple analytical and scientific entities.

• (U) Military personnel reported seeing five equidistant lights that they believed represented a potential incursion into restricted military airspace.

• (U) AARO's Intelligence and Science and Technology (S&I) partners independently came to the same conclusion in accordance with AARO's analytic framework.

• (U) The objects strongly correlated with specific commercial aircraft travelling on different air routes up to 300 nautical miles from the sensor.

(U) Case Essentials (U) Military personnel reported this case due to the observed UAP presenting a potential incursion into restricted airspace. The UAP were described as equidistant lights that flew at a relatively constant pace

(U) Location: Western United States military airspace (U) Date(s): 2021 (U) Altitude: Between 20,000 to 40,000 feet (U) Shape: Oblong dots/lights (U) Reporter: Military personnel (U) Sensor: Infrared (IR) (U) Behavior: Equidistant lights that flew at a relatively constant pace (U) Case Status: Resolved; the lights were aircraft up to 300NM away from the sensor
