i'm at drew & 19, i've been hearing these sounds for about a year now, at first i thought i was insane, but lately lots of people seem to be taking note.

it is most certainly not a train, a plane, construction, or anything like that. it sounds like a jet or rocket engine just constantly blasting in one position only changing to get louder or stop abruptly, only to resume shortly after, and then just stop.

always between about 1:40-4am, usually closer to 2am, occasionally between 12pm-2pm, always coming from the East/South East, tonight was the absolute worst it has ever been, it seemed to have an extra depth of loudness tonight, it almost seemed to have other secondary noises layered with in it.
