Driving to Buffalo eastbound on the I90. At approximately 1:30AM about 10 to 15 miles outside the city, a bright light appeared in the eastern sky and streaked rapidly downward and disappeared. I was talking to a family member through my vehicles audio system when it occurred and I was very surprised to see it so clearly. Upon further investigation, there have been several recent reports in Buffalo the past two months of fireball type UFOs being seen in various parts of the city. The whole encounter lasted under 3 seconds, and the object was moving extremely fast.
