Track on flightaware - Popes flight to JFK American AA9420 (flightaware.com) 기타...

If Flightaware or ATC flight data misses a position report, the software "assumes" that the aircraft is continuing on the same heading / speed of last report. When subsequent report(s) are rpocessed, the tracking line logic corrects to show the most likely (and usually accurate)track. Security, in this case, is not a factor.
I tracked that flight live and it was quite unusual. First, the tracking did not begin until more than 10 minutes after the plane had left Joint Base Andrews. Then the total flight time showed up as seven minutes -- which promptly was used up, and we went into overtime. Then the flight path showed an acute angle turn back toward Washington that continued for quite a while. Finally, things settled down, the angled regression disappeared, and the track showed up as it does now.
378 knots @ 10000 too....that would be a hoot!
Saw the same thing, most likely the position was being scrambled (To the general public ie: Flightaware) intentionally for security reasons.
most commercial are delayed in real time for security reasons
The Pope's flight from Cuba to Joint Base Andrews was pretty straightforward in the Flightaware tracking. It even showed several minutes of circling over North Carolina because he was way ahead of schedule.
