was not able to see the point where the object originated from as I was looking up out my window when the object came into view directly overhead. I was moving from SE to NW directly above me and went past the horizon. It was unbelievable!!

Remarks
Heard what I thought was a loud, low-flying airplane which prompted me to look up and this is when I saw object above. No airplanes could be seen at the same time.
