Unmarked aircraft are conspicuous by their effort to be inconspicuous.  I saw this SAAB 2000 parked up at the Clay Lacy ramp and, before too long, it taxied out and departed kindly backtracking passed me in the process.  SAAB 2000s are not overly common anyway so that was the first thing to notice but, since it was completely white, I figured it might belong to someone not advertising their presence.  Sure enough, it belongs to the Department of Justice.  I wonder what it was doing here?
