Mick West | Three Row UFO over the South China Sea - Probably Flares! @MickWest | Uploaded December 2021 | Updated October 2024, 16 hours ago.
These "UFOs" consisting of three diagonal rows of appearing and fading-away lights looks very confusing at first. But if you compare it to existing video of flares, then it all makes sense. Probably just three military planes dropping flares.
