I heard a long, low rumbling noise this afternoon, mid- afternoon. I opened a window and could not detect any direction it was coming from. It went on for several minutes and then just stopped. I am on the Jersey shore, but I don’t think it was a boat or plane. It did not change in intensity. I hear it last week as well. Anyone know what this is? Maybe something military?
