Picture this:  You’re relaxing after a stressful work day, kicked back in your recliner, adorned in your jammies, waiting for Matlock to start.  Suddenly, the entire neighborhood begins to tremble as you hear what sounds like and explosion in your living room.  The weird part?  There was no explosion and no explanation for the sound or tremors.   Unnerving, to say the least!   This week we take a look at mystery booms and “Sky quakes”.  Are these things caused by natural phenomena that occur in the earth and atmosphere?  Are they hargingers of an impending alien invasion?  Perhaps a top secret government construction project?   Give a listen and let us know what you think is behind this most mysterious mystery.
