Anomalous Object/Entity/Location Number: AOEL-917
Difficulty of Containment: High
Danger Level: Low
Containment Protocol: Any containment of AOEL-917 is technically challenging and beyond current capabilities. It is contained from greater awareness naturally in large part due to the ambient and similar sound-overlap with routine proceedings. Its theorized extension in spacetime is virtually contained due to its highly specific geolocation.
Anomaly Description: AOEL-917 is a mobile volume of sound waves. AOEL-917 spontaneously manifests at 11:20 p.m. UTC, every 29th of October upon a runway in Soekarno–Hatta International Airport in Jakarta, and demanifests at Depati Amir Airport in Pangkal Pinang at approximately 00:20 a.m. UTC the following day. The origin (departure) and terminal (arrival) points of AOEL-917 are identical with that of Lion Air Flight 610, a flight that took place on the 29th of October 2018. The Boeing 737 MAX plane of this flight collided with the Java Sea thirteen minutes after departure, killing everyone on board (189 individuals).
It is difficult to attain recordings and analysis of the contents of AOEL-917. A private flight is being scheduled in 2022 along AOEL-917's theorized flight path for as much further analysis as is possible.
AOEL-917 was discovered incidentally in 2019 by workers in both involved airports, who reported the sound of airplane engines despite no flights being scheduled for take-off or arrival at these specific times. The confusion resulted in numerous panicked calls to airport personnel requesting clarification of each event, which was dismissed shortly after radar confirmed the absence of departing or incoming aircraft. The AOEL Society discovered the correlation by collating independent tips from both events.
AOEL Society members were situated in 2020 and confirmed the anomaly's manifestation and demanifestation with audio recording devices. In 2021, members were present in waiting planes upon both the departure runway and would-be arrival runway of Lion Air Flight 610, and were able to capture brief seconds of audio that passed quickly through the stationary planes in the direction of a would-be flight. Analysis of this audio reveals routine voices and engine noise overlapped with the naturally present sounds.
An AOEL Society-procured boat was also situated near the crash coordinates in 2021. There was no explosion-like sound that would have accompanied the crashing of Lion Air Flight 610.
