I stopped at Boeing Field to make a couple of calls and I was pleasantly surprised to see that a Boeing T-38 chase jet was not far out.  I was able to get the camera out in good time for it to arrive and, even better, while there was plenty of cloud around, the sun popped out to allow me to get a reasonable shot.  I then went back to dealing with my calls.  I had noticed a USAF T-38 further east in the state but had assumed it was not coming my way.  However, I was wrong.  A short while later, it called up on approach.  The sun was less cooperative which was a shame for a gloom black painted jet but it was still good to shoot.  From expecting nothing to getting two T-38s in short order was a nice surprise.
