Summary : Giant white streak moving across the sky at a high rate of speed stopped and took a 90 degree turn and went straight up and eventually vanished into the night sky. It changed colors from a brilliant white to a pale bluish hue.

We were driving along Highway 11 at about 2 am at a rate of 55 miles per hour. In the northeast quadrant we saw a bright white object tht caught our eye because it was moving very quickly. it moved from the east to the west and stopped on a dime it looked to be enormous and might have been seen from quite a distance . We pulled the car over and got out to view it better. The object while it was stopped changed from the bright white light we originally saw changed to a bluish hue. It looked as though it was hovering over or near EROS Data Center. The cows in the field on the east side of the road seemed to be come nervous and start walking around. The object then darted off at a 90 degree angle and went straight up until it vanished.
