So i did post a fb post on this and many people from diff neighborhoods all around chicago felt/heard this at the same time around and all were confused but no one saw anything. Alot of people said it was like a low flying plane but more intense. I live by the lake and there are often planes that are kinda low going by. I was going up my stairs and heard it and felt the walls and windows shake and for a second i honestly panicked ...the "fuck this is it " panic. I thought a plane was about to crash. By the time i looked outside, nothing. Everyone else said the same thing. Ill paste some of the responses i got. BUT NO ONE SAW ANYTHING?!!!
ME: Was their a ufo or something yesterday night. What was that loud insane space craft sound? I thought a plane was gonna crash.
