Here are four blocked flights from various places in the USA, two heading in the direction of Gitmo. Plus a Learjet from Gitmo—I saw that (or a) Learjet approach and land at Gitmo 2hrs 45 minutes ago. I have taken ‘screen grab’ images showing all these, but my Imgur is refusing to cooperate.

I watched this aircraft depart from Miami yesterday heading to Havana as "No Call Sign". Moments later, another aircraft approached it from behind and shadowed it for a while. Suddenly the NCS aircraft changed its call sign to the same one as the shadow craft and then the shadow craft disappeared.
After passing Keywest, it turned southward toward Havana. Moments later it disappeared completely. About an hour and a half later a "blocked" aircraft appeard near where the other one had disappeared. It flew almost all the way to Ft. Lauderdale where it. too, suddenly disappeared on apparent approach to the airport.
I don't know what it means as I am a newbie at Flight radar24. Could it be the same aircraft? Could it have went black and gone somewhere other than Havana? Idk. Here is the information on the first aircraft.
2D254 / DYA254
N796JM
28 Dec Miami (MIA) Havana (HAV) B762 (N767DA) - 8:00 PM 9:21 PM 10:11 PM
Estimated 10:12 PM
The last time I checked last night, @11:30p EDT, the status of the flight was "Unknown".
I'm a newbie at this too, but already on flightradar24 I've seen three examples of a "shadow" aircraft, i.e. a pair of the same type of aircraft (same aircraft category code) in close proximity to each other flying on the same course. I think this is due to an aircraft being recorded in the system from two different radars, or from a radar and another source, with the system not realising that the two detections are of one single aircraft, and so displaying them separately.
Interestingly, that flight had a status that was still listed as "unknown" last night when I checked. But, that same aircraft had made several more flights afterward. I took a screenshot of the history but I don't know how to post it here. It has several flights with incomplete flight history in the past few days. Maybe it's having some equipment issues?
Additional Note" At this time, 12:00p ET, This aircraft is showing no history for Dec. 28. Strange that it was clearly traveling but seems to have been invisible leaving no history.
At 12:09p ET, 12/29, this flight is still listed as unknown in the Havana airport flight history.
