Sorry it took so long to reply,
1. The crash site is about 16 miles NW from the approach end of 21L, Near Mingus Mountain.
2. Tower told a few airplanes to "hold their position", and possibly yes, to "hold over Prescott". All that would mean is to litterally hold "circle" over Prescott. Tower told me to hold my position which was the fairgrounds, so thats where we circled for a few minutes. After they started accepting inbound traffic again, it was so saturated that Airplanes were only allowed to do full stop taxi backs or full stops. The Mig landed right after we landed on 21L and the trucks rolled right behind it to the south ramp where it was parked since the airshow.
