What I saw shone a light like I have never seen before or since and aerodynamic capabilities beyond what we have.

While driving back from Albuquerque on a crystal clear night I observed an object flying around Los Lunas hill.  Because of the moon light I could make out a dark object hovering and moving about.  As we got within about 5 miles the object lit up a part of the hill side with a light that did not look like any light I had ever seen.  The light was not instantaneous but moved toward the ground and then would go back up again.  It was also a differant color than one might imagine from a search light.  I woke up one of my sisters and pointed the object out.  We were within a mile of the hill now and the object(possibly round?) was moving around and occasionally shining the light downward.  As we got within a half a mile it rose approx. 500ft from the 100ft it was at and then accelerated at incredible speed SSW and disappeared.
Witness indicates that the date of the sighting is approximate.  PD
