Unusual sounds that seam to originate from the air with no visible signs of the source. The sounds have been reported as far back when the settlers where exploring America. The sounds range from explosions, loud sub bass frequency noise, trumpets like sound to metallic scraping. When the sound are reported in the media the "spin" will usually be to blame the sounds on a natural event of sonic booms caused by a jet. The people that experience the sounds will tell you otherwise.
