So this happened to me yesterday.
Last night I was hanging out with a few friends at home. Out of no where we heard a really loud boom, and the lamp shades in the room started to shake. It was really weird to say the least.
I did a little research, and apparently this has happened quite a bit in the last 10 years. Source
What do you guys think it was? A sonic boom? Possibly from a plane brought in to assist Boston?
