I was in my living room and happened to look out my window and seen a ball of light. just after i noticed the ball of light and started to observe it there was a very loud boom! it shook my whole house and was heard and felt about 3 blocks over. the ball of light then shot to the north of our location at an impossible rate of speed. i felt shocked at first but there was no mistaking this for any aircraft that i have ever seen the ability to hover and then take off at a high rate of speed left me baffled and wanting to learn more. me and my fiancé reported the event to our local news only to find at least 30 others who have indeed heard or seen the objects and sounds we have. there has been no official report but we did hear of increased police presents with out explanation a couple blocks from our house. no one will tell us why and everyone ignores all my questions. i an certain that what i seen was not part of this world or at least not part of any technology that has been released to the public. if it was of human origin the occupants of the craft would have pulled to many negative g's and died this object accelerated at a rate i have never seen. i lost sight of the object as it speed away.
