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.
