Here is one photo of both shuttles on their pads - the distant one over to the left is Endeavour, the then launch on need vehicle, and then Atlantis is closer and on the right of the picture.
Turns out I do have a few more pictures with both shuttles in view, but this is about the clearest I could manage with my little camera.
All of these shots are just with my small, hand held little pentax optio m60, so I'm pleased enough.
