Beijing Xijiao Airport

XiJiao is a Chinese military/governmental airport strategically positioned on the edge of the fourth ring road in downtown Beijing. It has few or no fighter aircraft, although a couple helicopters. Mainly you see 737's and occasionally a CRJ 200 or Gulfstream. Only time you see Airbuses here is when CUA airlines (Which is the only airline operating from NanYuan Airport) stop by occasionally. My guess is that they are contracting to transport officials or the likes. Plane spotting opportunities by the far south west corner of the runway in a small park, or at the two ends of the runway. Traffic usually is on workday mornings.
