I did track an unusual flight out of Europe a while back. The plane, a US Mil plane was not displaying any info on Flightradar24 but all info was on ADS-B exchange. Still use Flightradar24 when I want historical flights but mostly use ADS-B these days.
Thanks ! Its kinda creepy watching the plane in person n not seeing it on radar . Kek.
