Subsequent analysis combined longer-focal-length footage with regional flight data, revealing the point source to be a distant airliner. The trailing \"wake\" was a video-compression echo accentuated by sensor gain, not physical cavitation. AARO therefore categorised the observation as a **non-anomalous commercial aircraft** event.[^1]\n\n[Sensor A](https://www.dvidshub.net/video/880270/south-asian-object-1)\n\n### Second-angle confirmation (Sensor B)\n\nA second MQ-9 in the formation captured the same phenomenon from a different look angle with a longer focal length. Triangulation between both sensors and open-source ADS-B tracks tied the luminous point to a scheduled civil flight at cruise. The apparent \"wake\" again resolved to codec echo rather than condensate.\n\n[Sensor B](https://www.dvidshub.net/video/880271/south-asian-object-2)\n\n[^1]: [AARO Atmospheric Wake / South Asia case resolution](https://www.aaro.mil/Portals/136/PDFs/case_resolution_reports/Case_Resolution_of_Atmospheric_Wakes_508-02262024.pdf); [DVIDS Sensor A](https://www.dvidshub.net/video/880270/south-asian-object-1); [DVIDS Sensor B](https://www.dvidshub.net/video/880271/south-asian-object-2)","readingTime":"1 min read"},"relatedRecords":[],"citation":{"canonicalUrl":"https://disclosdex.com/events/2021-atmospheric-wake-south-asia-sensor1","title":"Atmospheric Wake / South Asian Object","publisher":"Disclosdex","retrievedFrom":"https://disclosdex.com/api/v1/events/2021-atmospheric-wake-south-asia-sensor1","license":"CC-BY-4.0"},"evidence":["Video"]}
