Why not Richmond? Maybe because it was considered unsuitable by the PIC.
From the preliminary report:
An AWS was also located at Richmond Aerodrome and the METAR issued at 0800 indicated that the wind was calm, the OAT 4º C, the dewpoint was 4º C, the visibility was 200 m with vertical visibility information being unavailable, and the QNH was 1033 hPa. An air traffic controller who was on duty in Richmond control tower later stated that the weather conditions at the aerodrome when the aircraft was flying over the Richmond area included a clear sky with a shallow fog that reduced visibility at ground level to 300 m.
