After a few days in which we had not tracked the drones, between last night and this morning no less than two drones took off from Sigonella.
The first, a NATO Northrop Grumman RQ-4D (reg. MM-AV-SA0014) carried out a mission over eastern Poland (but with the ADS-B transponder disconnected).
The second, an USAF Northrop Grumman RQ-4B (reg. 10-2045 – callsign FORTE11) took off from NAS Sigonella this morning and is now (10:30 CET) over the Black Sea to begin a surveillance mission.
