Did anybody hear the strange rumble that was going across the sky just a few minutes ago? It was heading west from Indiana toward Illinois. If it was thunder, it was like none I have ever heard before.
I would say it lasted for over 5 minutes at a steady rate as it traveled toward an area occupied by someone I know about twenty five minutes away. After talking to them, they claimed it did the same thing as it passed over them.

I live in Mo and the amount of lighting and thunder over the last serveral days since May 7th is the loudest I have ever felt or seen, my house shook for hours and I even recorded some of the unbelievable sights and sounds so I hear your concern hopefully the next couple of nights will get better
WOW I HEARD IT TOOO!!!
Im in arlington heights illinois.
It sounded almost like a sonic boom, louder than thunder. I looked in the sky right away and saw nothing...
I hope the op sees my post because I did hear it. I wanted to post it on here but was too tired.

It could be the US airforce testing a new "invisible" aircraft, just a thought. Anyone tried to map the apperance of the thunder/sound to known airbases in the US ? Yes i know those aircraft can cover some huge distance but not for that long at supersonic speed. /Cheers.

A very common source of long lasting, very loud but apparently inexplicable noises are power stations. Specifically coal fired power stations which operate high pressure steam turbines. Every so often, safety regulations require these facilities to test the high pressure safety valves. This causes an enormous racket, unlike anything most people are familiar with. Steam at several thousand psi is released into the atmospher creating a rumbling noise that can be heard for miles. This noise can last up to half an hour. If anyone ver hears such a noise, the first thing I would ask is, is there a power station within five miles?

This reminds me of the one time I was in Montreal and I went outside because it sounded like we were getting a storm. Turns out it was a beautiful night with no lightning or rain. We heard consistant [think thunder that doesn't end at all] for about an hour.
I started to panic a little thinking it was some kind of explosion.
