Great photos, Mike!
I had the good luck to get a tour of the orbiter Enterprise here at Edwards AFB when I was working on my masters thesis. I don't remember if it had flown yet or not. I don't think so.
There are a whole series of videos of the test program here
, many of them short. Most of them include the air-to-ground comm. Number 5 is interesting because it demonstrates how squirrely the vehicle's attitude control could be in the landing phase!
