" Strange Crackling Booming Sounds In The Sky North Central USA September 27th 2014Not sure what it was but today at 5:30am CST USA, I woke up to some very strange noises. Thought it was in the back so i went to look because that is where the noises were coming from. Then in the front, went to go look.. Then from the west, thought it might be my neighbor, then back towards the front and a little from the east. Well as clueless as i was.. I went outside to experience some very loud off and on crackling boom type sounds almost like thunder or fireworks but nothing of the sort in the area. At 5:30am? in central Minnesota.. and where I am nothing but roaming tiny hills, trees, grass etc.Then after about a half hour of listening to these sounds from all directions (neighbors were up wondering too) I went online to search and find something about it. Nothing from anywhere about anything. The noises lasted till about 9am then slowed and eventually stopped. I continued to search Google for hours to find nothing still. 3:20pm now and I came across this page, figured I'd post this and see what others think or if they could determine what the hell that was?!!! Thanks in advance Nothing was seen, only heard.Skies clear, no Airports near, no storms near, no fireworks or any reason to have any(didn't sound like them though), sky looked normal as usual. Not sure what other details to provide.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD)) "
