Glowing white sphere moving rapidly west to east high rate of speed and absolutely silent. Phoenix PD confirmed sightings

Gentlemen, I'm trying to locate information on a sighting I had in Phoenix on Mother's day 1990 or 1991 around 10:00pm. I had even called the Phoenix PD to ask if anyone else had seen this and the dispatcher said, "I don't know what you saw but I've been getting calls from all over the place." I was living at the Tampico apartment complex(6130 N. 7th. Steet) just a block north of 7th street and Bethany Home Road. It was Mother's day (May 11th) at approx. 10 or 10:30 pm. A glowing white sphere traveling from West to East crossed overhead moving rapidly and in a perfectly straight line and went out of sight quickly. I was on the Army Parachute Team in West Germany and have jumped out of allot of aircraft in my career. I know how to judge altitude and speed fairly well. This object was about 1500 to 2000 ft. up and absolutely silent. It did not project light in front of it (like running lights on an aircraft) it simply glowed white. There was a discussion on two talk shows the next day about the incident.
Date is approximate.  PD
