Tremendous rumbling in the NW suburbs of Chicago

[Strange Sounds]

I heard a tremendous rumbling in the NW suburbs of Chicago in the early hours of Tuesday, April 18th, 2017 at around 3 AM. It was a long, sustained rumbling, very deep, almost like the sound a massive garbage can would make if it was dragged across the ground. This was definitely not the standard engine noise from O’Hare: I hear airplane and construction sounds from there all the time (and have heard them for many years), and nothing was ever this loud. It practically shook the house, and it lasted for around half a minute or more.

Very interesting… You posted last time articles about booms one by one, and now you have heard something personally. Are those phenomena expanding?

Sorr, but it is not from me. I live in Europe. I was a comment posted on the blog and as it is sometimes hard to find comments I decided to publish it here.
