does the data at: https://flightaware.com/live/flight/N666HD/history/20171104/1500Z/KLGB/KLGB/route

indicate that actual flight taken or the preflight plan?

seems to me it was a planned flight

that plane seems to be moving:

Is there anywhere that either of the Podestas are regularly active? Facebook or Twitter or something? Is there any indication of normal activity on either of their parts?
