Leaving my girlfriend's grandparents house, noticed a blinking whitish light moving to the northwest. Thought that it was a plane, but didn't see the typical navigation lights or hear the engine(s). I got into the car and drove. I was on 44th Street and as I approached Indian School, I saw it again, moving in the same direction, very slowly. Must be a plane, I thought to myself. Trying to navigate, but periodically looking towards the sky, I could still see it as I approached Camelback Road. I watched it as it passed near a plane with the standard navigation and strobe lights. It continued the same heading as we approached the area where 44th Street curves to the east and changes into McDonald. Turned left on Tatum and I couldn't see it anymore. As I drove deeper into Paradise Valley, passed Lincoln, I saw it again, same or similar light, blinking and moving slowly. I saw this thing in the sky until I reached my home on the otherside of the Paradise Valley Mall. After I parked my car, I couldn't see it anymore.
