I took my yorkie outside to go to the bathroom, and see where a very loud, pressing humming was coming from, but could not see anything outside. i asked my son, michael if he could see where the sound was coming from. then the sound stopped, and above us was a massive thing, larger than any plane or jet i had ever seen. it was solid gray, with a dim light on it’s belly. from underneath it looked like a huge silhouette of a great white shark above us, floating slowly across the sky. we both stood there , and stared at it as it slowly floated toward the south. and then it was gone. i asked my son what he thought that thing was and he said some kind of plane, but no plan could fly just above the tree line, or that slowly. i won’t put a name to it, but i believe it was not made by human hands.
