When we were outside this morning we noted a helicopter fly over about a mile of two from our house. What made it different was that it was trailing a cone shaped object by cable with the large end of the mesh cone aimed toward the ground. We couldn't figure out what it was doing as it clearly wasn't anything hat could hold water. It looked like an upside mesh cone and we were hoping they were hunting down the crazies in our community to relocate them.
No such luck because when the tractor repairman was here checking out our tractor the helicopter came back with that upside cone hanging under it. He recognized what it was doing immediately as he once met a pilot who told him that rig was checking the depth of potential sub terrain faults that could shift to cause earthquakes. Its good to know they keep up on fault lines but sadly we are still stuck with the crazies in our community.
