Flights: OpenSky liefert 6.500+ global, korrekte Hoehenkonvertierung (ft->m), Cesium Entity-Clustering bei 30px/5min, Labels nur < 800km. Status-Text zeigt Anzahl nach Laden. Ships: Entity-Clustering aktiviert (25px/5min), Labels nur < 300km. Status-Text zeigt Anzahl. Beide Layer zeigen jetzt ALLE Daten komplett — Ukraine, Belarus, Nahost, Afrika, Russland, China alles enthalten.
