1995 Phoenix SE Valley "shooting star" turns 90° and crosses sky in couple of seconds.

I stepped out onto my patio around 10 pm because I'd heard there was to be a bit of a meteor shower and I wondered if I could see any of it from my somewhat rural location.  The sky was full of stars but I wasn't seeing much in the way of shooting stars, so after a few minutes I was ready to give up and go inside.
That's when I noticed a star moving very fast from east to west across the sky. By my estimation it could have crossed the entire sky in 5 or 10 seconds. At first I thought maybe it was a satellite.  I've never seen one before but it just popped into my head that must be what this is, and I remember feeling a bit proud of myself for figuring it out.  At least that seemed like a pretty good guess until it got about 75% across the sky moving due west when it suddenly turned north and just took off so fast it was across the sky in a couple of seconds and gone.
I don't know much about space but I don't think satellites can turn or move like that, so for me - this was a UFO.  It was flying and I couldn't identify it, put it that way.  Like probably millions of people, I never told anyone about it.  It's not dramatic or exciting but sometimes I wonder how different the world view would be if everyone who's seen a UFO would submit a report and I couldn't keep refusing to report my sighting with that thought in my mind.
 Date and time are approximate, sorry but it was over 10 years ago now.
Witness indicates that the date of the event is approximate.  PD
