Brilliant object moving at right angles at high speed from the ground, instant acceleration!

I am a 52 year old power company lineman with four children and one grandchild. I have never really believed in UFOs or anything of that nature. No Proof. What me and my fellow worker saw on a totaly bright, sunny afternoon in upstate New York, blew my mind! We have only mentioned it once to our co-workers (which was met with laughter) and to our own families (with raised eye brows from them).The two of us don't even mention it anymore to each other but it has bothered me for over 20 years. I've been in the utility business now for over 30 years and have worked all kinds of hours day and night. I have never seen anything like what I am about to describe to you.
I never wrote the date down but I think the month and year may be close. As we were driving south on Interstate Route 81 just about a half mile north of the Preble exit we both saw ,at the same time, A tremendously brilliant (chrome like/brilliant white) object with no decernable shape, possibly round about the size of a small car, slowly rise straight from the ground to a height of about two hundred feet, pause fo a second and then accelorate instantly at a slight angle from east to west over the southbound exit at Preble. It went from a DEAD STOP to instant acceleration. A BLUR in a fraction of a second. We could see the blur for about the first hundred feet or so. I know of nothing that could stand those forces. I was the passenger in the car and my buddy was the driver. We both looked at each other and I said to him "did you see that?" He said " I didn't see anything like that", as if to say he wasn't going to repeat it. This was the middle of the day! Other people had to have seen it too. I still see the event clearly in my mind as if it were yesterday. I never said to anyone that it was a "fling saucer" or anything of that nature. I don't know what it was, but is WAS THERE. We both saw it and I'll swear to the Pope and to God himself what I just described to you. I'm a very private person and I DO NOT want any press on this. I'd tell them that I never saw it but someone should be investigating these things. Maybe it's some type of unknown geophysical event, I don't know but this traveled at various speeds and right angles. I'm stumped.
Date is approximate.  PD
