I was in Miami between 12/18 and 12/20. I sadly had to use MIA and American instead of FLL and VX.

On my return flight, on 12/20, I noticed a VX bird in a hangar located to the side of one of the runways. Any insight as to why? I couldn't find any info via flight tracking services, but I also didn't look exhaustively.

Could it be a diversion from FLL? A private charter? A flight to bring VX staff out to meet with MIA staff prior to launching LGA-MIA?
