Object seen manuvering around the area of Namaeo Airforce base from the vehicle I was a a passenger in.

Estimated range was about 5 kilometers. Object accelerated and decelerated at very high "G"s. Object also changed color while performing manuevers = from a orange=white to red to green to blue and at random. 
Our vehicle was traveling northbound towards the small town of Saint Albert. The base is east of the highway. Night sky was clear and weather was typically warm and dry. 
Sighting reports of "lights in the sky" were printed in the next day's local paper. I recall at the moment the object accelerated towards the vehicle a distinct feeling of fear when it stopped. 
The object accelerated away at a tremendously high G towards the northeast.
