I have never photographed at Luke AFB before.  Mark and I spent a few hours there as part of our trip.  The base is home to the F-35A training unit and a variety of foreign F-35A training too.  Plenty of USAF F-35s were in the pattern that day.  I got loads of shots of the based jets but, with the current style of low observability finishes, the jets did look very alike.  Yes, there were crew names and unit badges to be seen but, sadly, one Luke F-35 looks a lot like another Luke F-35.
