A strange roaring sound was felt by residents of Beloit, Milton, Evansville, Albany, Monticello and Monroe as well as Janesville in southern Wisconsin on April 19, 2015.
The still mysterious noise was louder and longer than an airline plane and even made some house vibrate.
As you might know, roaring sounds have been attributed to meteors in the past. Moreover, the Lyrids meteor shower has started mid-April 2015. So a meteor explosion could really be the source of this boom.
The National Weather Service in Sullivan had no radar contacts or weather events that might explain the noise. Just weird!
