A large fireball was spotted by webcams and visible as far away as Missouri and Indiana. National Weather service Radar picked up a strange echo just 5 miles north of where I live.

I heard the sonic boom myself and it shook the apartment building. I looked out to see if there was any lightning thinking there was a storm (though nothing was forcast) and then looked at the radars from NWS - to find nothing but ground clutter. I figured then it was a sonic boom.
Why do these spectacular phenomena always take place halfway across the country from where I live? :banghead:
Some pieces have been found and will be displayed:
Midwest meteorite fragments to be shown at University of Wisconsin Geology Museum (http://www.greenbaypressgazette.com/article/20100419/GPG0101/100419128/1207/GPG01/Meteorite-fragments-to-be-shown-at-UW-Geology-Museum)
On the night that happened, I saw a flash of light for a few seconds, then a few seconds later, heard the sonic boom. I thought we were having a thunderstorm, so I went around and closed all the windows in the house, only to look up at the sky a few minutes later and see no clouds and I could see the stars. So I figured something else must be going on. Wasn't til I turned on the news the next morning that I heard it was a meteor. I never did see the actual meteor itself, I wish I had looked outside sooner. The debris field is just a few miles from where I live in SW Wisconsin. I haven't found any pieces, yet.
