Black Triangle Sighting in New York, New York on 2017-06-15 00:00:00 - Delta shaped object, jet engine noise upon approach and abruptly ceasing after fly by. well illuminated.

Watching tv and heard distinct jet engine type noise approach. gave impression of low flying jet aircraft. initially dismissed as atmospheric distortion of commercial jet. noise increased to point where it warranted attention as it seemed as if it could be very close to house. went to back deck and observed object that was very well illuminated with several white/blue light emitting areas that suggested a delta shape solid body shape. object heading west to east or slightly nw to se. object maybe 500-600 ft. altitude. observed to see if object would have catastrophic event i.E. crash. no flash or sound to indicate that possibility. jet engine noise did not fade gradually, but abruptly ceased app.10 seconds after passing. neighbor heard object but did not see. also confirmed low flying aircraft impression. not sure of exact time but i believe after 11pm. thought it might have been stealth aircraft. heavy illumination and abrupt sound seizure contradict that logic. object appeared not to be travelling at a speed in excess of 100mph and was very large for low level speed. lost site of object through tree canopy. i wear glasses and view was only for about 10 seconds in total. recollection of delta/triangle shape pretty firm. light emitting areas may have been round and rather large. i noticed no obvious beams or shafts of light coming from them and no reflection of light from below. neighbor confirmed hearing engine noise and impression of low flying aircraft. did not see object and dismissed event upon cessation of noise. he resides 1/4 mile north.
