It did but flight trackers show it originating in a neighborhood north of Langley. The likely reason for this is that the aircraft didn’t have ADS-B for tracking. Instead it’s using Mode-S. Flight trackers use a triangulation method called MLAT to track flights like PAT25 (the blackhawk’s callsign). However this method isn’t nearly as accurate as ADS-B.
Conspiracy theorists are saying the flight originated from the Saudi embassy, north of Langley. I’m not sure if the embassy is actually located there, I don’t really care either. I just know people will do all kinds of things to either profit or gain attention over other people’s misery.
