I was driving home from work on dec. 20, 2017. it had finished at work at 4:30, and it is about an hours drive (give or take depending on road conditions and traffic) to parents place where i was staying for the month of december. it was somewhere between 5:30-6pm i was about 2 minutes away from my parents house, and out of the corner of my eye, through some thin tree tops, i saw a bright blue/white oval shaped object high in the sky. my initial thought was that it was an airplane, but the brightness and shape of it made me due an immediate double take a half a second after my initial thought. as i looked back up at it, it was moving just beyond the thin tree tops that were preventing me from getting a fully clear view of it (it's not that the object was at tree top height, it was much higher, but at the angle i was viewing it the tops of the trees nearest the road side somewhat blocked it.)at this point i had a clear view of it, and in my amazement i slowed the car to an almost complete stop in the middle of the road. i watched it as it looked like it was travelling south at about the speed of a passenger plane you would see in the sky. then, in a split second, it zipped away south east at an impossible speed, over the hills on the horizon and out of site. i left a brief trail as it zipped away. i can't even say that it accelerated, it simply changed speeds in an instant.
