I was in bed using my phone when i heard a humming sound that caught my attention and i looked out my window to see lights flashing on an object low enough to be somewhat visible, lower then iâ€™ve seen any non-biplane fly here. i rushed to put on my glasses and watched it. it seemed to be triangular or chevron in shale based on the positioning of its lights. it had white and red lights, some of which seemed to flash regularly. there was an audible humming which drew my attention and grew fainted as it grew distant. it was close enough that i could clearly see its lights and a pattern to them and closer then any plane iâ€™ve seen, aside from the occasional biplane. it seemed to be curving its trajectory in flight and while i was surprised at how quickly it changed direction, there was visibly gradual movement. the point of the chevron/triangle shape was going forwards along the flight. i watched it until it was beyond the line of sight allowed by my window. i heard it humming for several moments further. i acknowledge that it may simply have been a low flying plane; but the shape, time, and ready movement seemed odd to me. this is why i felt it was worthwhile to make a report, on the off chance others saw the same thing.
